17 plumbing & drainage mistakes that will lead to terrible problems

plumbing & drainage mistakes


1. Lack of vents and traps


All drain fixtures must have appropriate vent. It is easy to combine vents for multiple fixtures but one should follow the requirements of the Indian Plumbing Code. Every trap should have a vent. You do not want water to be siphoned out (which leaves the trap dry and useless).

Traps with proper water-seal as prescribed by the Indian plumbing code only should be used.

2. Too much or too little slope



Too much slope will not make things easier. Liquids move faster than solids at a slope, leaving the opportunity for solids to be left behind (causing major disruptions in the future).

The ideal slope is about 1°. The drain line should be a full size pipe with a slope to the drain without any valves between the drain and the outlet. The flow path should be smooth and it is always recommended to use a male to female type of pipe fitting combination.


3. Improper amount of fixtures per plumbing vent


Having improper number of fixtures connected to one plumbing vent may cause siphonage problems causing blow outs. One common error is when more fixtures units are connected to a small vent pipe. 


4. Wrong location or wrong amount of cleanouts


It is very common that cleanouts (Rodding Eye or Cleaning Doors) are being placed in a location that is not the best for them. It is extremely important to have the required clearance before servicing a line when it gets clogged. You should consider cleanouts on convenient to reach locations depending on how the line was designed. This will facilitate servicing the line. Cleanouts are usually “required at the base of each sanitary stack.


5. Tight space around toilets


This will cause discomfort to users and issues with servicing. The toilet/WC must be at least 15 inches from the side wall and at least 18 inches from the wall in front of the equipment.


6. Location of pressure relief valves


Pressure release valves must be adequately provided especially in case of high rise buildings to protect internal devices from damages and inconvenience to users due to high pressure. Further these must also be placed where they can be easily reached and serviced.


7. Connecting dissimilar pipes


These mistakes can sometimes lead to some serious problems. A galvanized metal pipe should never be connected to a copper pipe (these metals do not interact very well together, and as a result corrode very quickly when they are together).

Try using some type of brass, or another type of fitting that is suitable to connect to a galvanized metal pipe. Similarly take precautions while connecting plastic pipes with galvanised iron pipes. Use threaded connection preferably with metal inserts. 

8. Cracked & loose pipes

Cracks in the drain pipes and waste water pipes leads to seepage of dirty water and sewer gases in to your bathroom. This seepage causes foul smell in your bathroom. Cracks in water pipes will lead to leakages and seepage in your walls and floors.

9. Dirty bathroom

One very basis reason of foul smell is your bathroom is a dirty bathroom. If you do not clean and sanitize your bathroom regularly , then germs and bacteria grow in your bathroom. This bacterial growth on the toilet seat, wash basin, dirty floor produces bad smell. Clean your bathroom regularly and keep it fresh and germ free.


10. Wrong location of air-release valves


Air release valves must be placed where ever there is possibility of air entrapment. Avoidance or wrong location can result in catastrophic failure of pipes and severe damage to the building.


11. Wrong solvent cement


Different piping systems require different solvent cements for jointing. Wrong cements will cause improper jointing which will eventually open up and leak. Proper solvent cement must be selected based on the pipe type and application.  


12. Criss-cross piping inside bathrooms


While installation of bathroom accessories, it is common issue that while drilling holes, pipes get damaged which leak and require breaking of the wall to repair. It is essential that pipes are laid out square and at levels where usually other kinds of installation work is not required once plumbing is done.


13. Inaccessible location of valves


Wrong location of a valve renders it completely useless at the time when it is most required. Valves must be placed at easily accessible areas. 


14. No expansion-contraction provisions


All pipes expand and contract with temperature. If adequate precautions are not taken, either the whole pipeline will snake and put unusual amounts of stress on the joints. 


15. No gap between pipes in stacks


A common mistake which results in servicing issues whenever a problem occurs. Adequate space must be provided so that in case repairs are required, all pipes are easily accessible and workable.


16. Not paining or protecting exposed piping


Depending upon material, most exposed piping will become brittle with time and break easily with slightest of impacts. Some materials would even lose their physical properties and fail. It is recommended that all exposed piping be painted with compatible paints for protection against UV.


17. Improper clamping of pipes and pipe supports


Improper clamping and support of pipe shall also lead to pipes sagging causing stress on the joints which may fail with time.

4 Major reasons for using Plastic Pipes for Plumbing and drainage over other alternates

Pipes Used In Construction Ajay Pipes

If you’re considering installing new plumbing or re-plumbing a house, one of the major decisions is which type of plumbing to use. Lead is of course out due to the health concerns. Copper, iron, bronze and galvanized pipe are still in use. However, plastic pipes come with a number of advantages that should make it the default solution for most situations.

Polyvinyl chloride or PVC pipe can be used for nearly every application, including drain pipes, cold water supply lines and vents. CPVC or chlorinated polyvinyl chloride pipe is better suited for hot water lines due to its greater heat resistance. Let’s look at the advantages of plastic pipes over the alternatives in plumbing systems.


Metal pipes can corrode over time. Iron, of course, will rust. Copper pipes can corrode when exposed to rust from a corroding hot water heater; this can contaminate your drinking water. Any metal pipe will degrade over time due to oxidation. All pipes can wear down due to cavitation or excessive pressure at one point, but it is easier to replace plastic pipe than metal pipe. Simply unscrew the connections and install a new one. Compare that to metal pipe that often has to be cut with a metal saw, new pieces installed, and all of it welded into place.


Another advantage of plastic pipe is how resilient it is. It will resist corrosion almost anywhere, including when it is buried under your yard or embedded in a concrete slab. This explains why the pipes running to your septic system or sewer line are almost always plastic regardless of the type of pipes inside your home.

While the minerals that make water hard can build up inside of any type of pipe, the smooth inner surface and overall resistance to wear mean it takes much longer for water scale to clog your pipes. Your plastic pipes will therefore work far longer before you have to deal with water pressure drops due to mineral buildup.

Water Safety

PVC pipe (lead free) is always safe to have in contact with your drinking water. It is non-toxic. A little rust in your water isn’t going to hurt you, but corrosion from your copper pipes due to the rusting connections upstream can cause problems. CPVC will last even longer than conventional PVC pipes. In every case, PVC pipes won’t leave that metallic taste metal pipes can give your water. The fact that PVC pipes are less likely to develop pitting can improve your water safety by not giving bacteria a breeding ground within the pipes themselves.


A clear benefit of plastic pipes is their lower overall price. They’re cheaper to make than metal pipes. They cost less to transport, as well. The lower price of plastic pipes provides a number of side benefits for homeowners. For example, because they’re so cheap, stores are willing to continually stock a variety of sizes. You can almost always find cheap replacement parts for sections of pipe, connectors and angles. A potential benefit of plastic pipes is that a homeowner could replace a cracked pipe or leaking portion on their own instead of calling in a plumber with the necessary tools to fix it.




The numerous advantages of plastic pipes mean that they should be your first choice when it comes to piping. Do your research and find out which type of PVC or CPVC pipes are best for your particular project.

How Plumbing and Drainage Relates to Your Most Basic Needs

Maslow’s hierarchy of needs is a list of essentials we need for life followed by other desires and needs. The most basic needs are food, water, shelter, sleep and air. What happens when someone falls violently ill due to a lack of clean water or because they don’t have working waste management systems? This is how plumbing and drainage is related to your most basic needs. You can’t move on to higher requirements like safety, love and self- actualization without fulfilling these requirements of life.


If you don’t maintain your plumbing system, the very air you breathe could become toxic. The release of sewer gas into your home can make your family sick.

Overflowing water from a backed up toilet or broken pipe damages your home, your shelter. If it isn’t dried out fast enough or happens repeatedly, the mold growth this fosters can impact your family’s health. Whether you suffer breathing problems or simply hate the smell of mold, it affects your quality of life. If you’re already dealing with chronic mold, call a plumber to find the cracked pipe that may be contributing to the problem so they can fix it.


Overflowing waste is even worse than clean floodwater. The dirty water containing human waste, food waste and cleaning chemicals carries it across your floor where it seeps into the carpets and walls. Now you have to worry about being made ill by both the bacteria this feeds that you could breathe in and the mold it nurtures. This is why you cannot afford not to have it fixed as soon as you suspect that your sewer line is clogged or septic tank is starting to back flow. You need to call a plumber when those sudden, unexpected clogs occur, too, such as when your toddler learns how funny it looks to flush toys down the toilet. Address these issues sooner rather than later, since a clog will cause more material to collect behind it until the system overflows. Fix it now, and you’ll get that toy or hair ball out. Wait a few days, and it will be compounded by human waste, hair, food particles and toilet paper. The mess that overflows will become more hazardous to your health.


Water quality is something that is not fully appreciated in developing nations such as India. People worry about fluoride and chlorine in the water and the luxury of how water tastes, forgetting that historically up to half of all children died before the age of five primarily due to water borne illnesses. Water quality can have major health consequences in the developing world. Rusting pipes and water pipes that let dirt seep into the line, discolor the water and pose a serious health risk. A water heater that isn’t set at the right temperature or malfunctions becomes a breeding ground for bacteria.


Tree roots often block sewer pipes and water lines. The moisture from the pipe attracts the roots until they start to grow into the line; this issue is worse for sewer lines due to the extra nutrients they carry. That will start to dam everything that you’re trying to flush away. Instead of repeatedly flushing the toilet or pouring chemicals down the drain, have a plumber run a checking-snake down the line to clear the roots or use an environmentally safe drain cleaner that will work if tree roots are the problem.


By maintaining the plumbing and drainage system well, you’ll enjoy safe, clean drinking water and waste elimination. You can sleep easier, too, knowing that you don’t have to worry about toxic messes that endanger your family’s health.

Green Plumbing

Plumbing is the most important product that you install while building your home. One leakage can cause immense amount of damage and loss for the home owner. One wrong decision can give you a headache for life. Here are a few tips that will prevent such problems.


Always check the credentials of your retailer. The retailer must be authorised by the company.


As much as possible, buy all pipes and fittings from a single brand only. Sometimes products from different brands may not be compatible and may cause installation and performance issues.


After installation insist on pressure testing of the entire plumbing system as per the manufacturers recommendation before back-filling of pipes inside the walls. The biggest reason for leakages and issues later on can be due poor workmanship which will generally show up during pressure testing. In case of drainage system, insist on doing leakage test. This will avoid the very expensive and time consuming walls and floor breakage later after finishing work.



Lead is a commonly used ingredient in plumbing pipes and fittings which has long term adverse health effects and can specially impacts infants and children. Some of these harmful ingredients can leach into water and cannot even be removed by R.O. systems. Always ensure that plumbing pipes and fittings you are using are free from lead and other heavy metals.

Solvent cements (fusion compounds) form a very small part of your plumbing system however is of prime importance in making a good joint. Certified solvent cements specially those complying with standards. NSF certified products are usually found to give best performance.


Always use metal insert fittings with all your end connections with your bathroom fittings like taps, showers heads, faucets, and other fixtures. Plastic threaded connections are cheap however can crack easily and are also prone to leakage with hot and cold water. Metal insert fittings are much more robust and will always give long service life.


It is best to avoid use of more than one type of pipe inside the toilet. It is highly recommended that all plumbing inside the toilet be done only with hot water piping to avoid plumber mistakes and other long term issues.


Ensure that plumbing and drainage pipes are properly clamped as per the manufacturers recommendations. This helps avoid leakages, damages and breakages in the long run.


Always paint all pipes that are exposed to sunlight. This will avoid damages to pipeline due to brittleness and ensure long life of the product.


In case moving into pre-built space, always take and keep inside the toilet plumbing drawing with you. This will help you locate pipes behind the walls so that if you need to mount something on your walls, there is no danger of drilling through the pipes and causing huge damage.


Ensure that the main trap inside each toilet/bathroom and kitchen has 50 mm water seal. Each bathroom, toilet or kitchen must have a master trap which connects all the pipes inside to the main or vertical drain lines outside the rooms. Before installing the traps, always ensure that they have minimum 50 mm water-seal. Check manufacturers catalogue for details before purchasing.
