Finding & Fixing Toilet Leaks: A Handy Guide For Your Convenience

If you find water on your bathroom floor, look for most common causes before you start to panic.

How to start looking for the causes of toilet leaks?


Tank sweating can be one of the common causes. This mostly occurs due to the difference in the temperature of the water inside the tank, which is generally cold and the temperature of the air outside the tank in the bathroom, which is very often warm and steamy. Most of the plumbers This causes the vapors present in the air in the bathroom to condense when they come in touch with the cold surface of the tank. This may drip and show as water on the surface.

Still, if you are not sure, wipe the outside of the tank with a towel and wipe absolutely dry. Now, watch visually if the tank’s outer surface is gathering droplets of water that tend to slowly drip on the floor.


You can use toilet tank liners or anti-sweat toilet tanks that mix cold and warm water coming into the tank.

Leakage from inside the tank

Once you are sure that condensation is not the cause, then next step to begin would be to check the tank for any kind of leakage.

Remove the lid of the tank carefully, and add any food coloring to the tank water. Do not flush the toilet, and wait for the color to mix and settle down. After 10 to 15 minutes, if you find colored water on the floor, it would indicate the leakage from inside. Check for cracks in the porcelain tank, leaks around the bolts and rubber seals, leaks between the tank and the bowl or from the gasket where the flush valve allows water to enter the bowl.


  • If the leaking is between the tank and the bowl, then you need a new tank-to-bowl sponge gasket or new washers or bowl bolts for the tank. It is very difficult to pin point whether you need to change the gasket, washers or bolt sets as all toilet bowls differ in structure. Best would be to change all to be on safer side until you are very sure.
  • Shank gasket is attached to fill valve on the inside of the tank. If there are no cracks in the tank, just tighten the shank nut. If the leak doesn’t stop, then you need to change the shank gasket.
  • When the fitting of the fill valve gets loose, or the rubber seal that keeps the water in tank from draining out gets old, leakage occurs. Replacement is the only option if fill valve stops working.
  • With high regrets, if the tank has any crack, there is no other option than to change the tank.

Other Possibilities

  • If the shut off valve is leaking, try to tighten the valve of the plumbing, else it has to be replaced.
  • Check for any leakage at the nuts on each end of the supply line. Water inlet at fill valve and shut off valve may need replacement of supply washers.
  • If you notice waste water flowing back and seep past the wax ring, a new wax ring may fix the problem. But, if the problem persists, then a blockage in the waste drain line shows higher probability. A professional help can only clear the blockage.

Everything That One Needs To Know About Drainage Systems

The right drainage system plays a very crucial role on the prosperity of a family as well as the easy going of day to day life. Wrong design of the drainage system or minor dysfunction leads to catastrophe. Now let’s discuss all the aspects of a proper drainage system, everything that one needs to know about it.

Plumber Toronto usually categorize drainage systems into various types and layers, depending on the construction layout. Like soil and waste pipe systems above ground, special application disposal system and basement drainage disposal system. When installing multi functional drainage systems, the piping system has to be installed on the basis of perfect hydraulic and engineering system.

Now, throwing some light on the parameters, one has to take care of when designing a soil and waste pipe system. The fixtures need to be provided with water seal trap so as unwanted pests, poisonous gas, microbes, etc do not enter into the system from the connected main swear to the building.

The sloping of the pipe, the inclination or declination angle at which they are connected has to be very precise and adequate for disposal system to be adequate.

Then coming to the ventilation part, the foul gases has to be removed. Ventilation determines the air pressure inside the system, now negative air pressure gradient is to be avoided at any cost as it will lead to suction and eventually clogging or retardation of flow. Under no circumstances the water supply pipe and the discharge pipe should form any cross connection. If that happens, there will be backflow of water, leading to contamination of the entire water supply.

The bends and junctions in the pipe should be very rounded and smooth. If necessary, clean out plugs has to be installed now and then or take the help from plumber Toronto. The material check of the pipe installed is to be confirmed, so as it is capable of withstanding the high pressure of the flowing water. Considering all the points above, the process does gets a bit costly but then, one has to remember drainage system is once in a life time investment, every care has to be taken for it to be perfectly functional.

Layout of the drainage system is again a very complex process. It totally depends on the geographical and topographical layout of the place chosen as the construction site. Highly trained professionals should be endowed with the responsibility of designing the blueprint of the drainage system. Local designers and architect should be chosen, as they are well acquainted with the region, if necessary multiple opinions about the layout is suggested just as  to be sure of efficiency of the plan.

As technology innovation is at high, many unconventional drainage systems are cropping up. Like self-cleaning system instead of manual cleaning. As the system gets more complex, leak detection techniques by determining the pressure difference is also present, Corrosion free pipes etc, adds edge to the existing drainage system. So invest right and invest smart in your drainage system.
