What is a drains test?

A drains test is a test performed to determine the condition of the storm and foul (sewer) pipes.

Why get a drains test?

Peoples reasons vary; house buyers do not want to buy someone else’s problems. A drain test may highlight problems such as blocked pipes and leakages in the pipes. Also a drains test may find the cause of any offending smells and source the cause of any cracking in houses. Furthermore new houses are not exempt from drain problems. Independent drain testing retrieved 51 drain rods from a newly built house. The house buyers stated that the drains had been blocking up consistently from the day it was purchased. See gallery.

How to Test Drain Pipes

A drain pipe test ensures the pipe is sufficiently watertight. This prevents the pipe from leaking its contents into the surrounding soil and potentially overloading or contaminating the local water table. When laying new pipes, it is essential to test them before the trenches in which they are laid are back-filled with soil, as this saves you a lot of time and effort in digging them back up again should they fail.

- Clean the end of the pipe that will be tested to remove any dirt or other debris that could affect getting an air tight seal. Place the bung stopper in the end of the pipe. Turn the wing nut on the stopper until it cannot turn any more, to expand the stopper and create an air tight seal. Seal off any branches on the pipe with more bungs.

- Connect the hand pump to the hose via the T-piece connector. Connect one end of the hose to the manometer. Fix the hose nipple in place on the stopper in the pipe, to allow the hose to be attached. Connect the free end of the hose to the hose nipple.

- Squeeze the hand pump to increase the air pressure in the pipe until the level on the manometer reads between 5 and 6 inches. Close the control valve on the hand pump. Let the pipe stand for 10 minutes to level off temperature and pressure in the system.

- Open the control valve and allow the pressure to drop so the manometer reads 3.93 inches. Close the control valve again and leave the pipe for five minutes. If after this time the pressure in the pipe has not dropped below 2.95 inches, the pipe is sealed correctly. If the pipe fails this air test, run a water pressure test to check its seals again.

Water Test

- Seal off all branches of the pipe with bung stoppers. Seal off the lower, or downstream, end of the pipe to be tested with another bung stopper, as if creating an airtight seal. Connect the 90 degree pipe bend to the other end of the pipe, which is the upstream end.

- Connect the 5-foot length of pipe to this bend to create a vertical pipe configuration. Either fasten this vertical section to your support struts with the rope, or brace it between two supports. The idea is to prevent the pipe falling over under its own weight when water is added.

- Fill the pipe with water and leave to stand for two hours to allow time for any trapped air to bubble out of the system. Inspect the level of water in the vertical pipe and ensure it is to a depth of 4.92 feet. Leave for 30 minutes, topping up the water as required to maintain a level of 4.92 feet.

- Record the total amount of water added each time the pipe needs topping-up. Sum up these values. If the total is less than 0.88 pints per 3.28 feet of pipe, not including the 90 degree bend or the vertical pipe, the pipe has passed the water test. If it exceeds this amount, the pipe is not watertight and the seals between each section of the pipe should be tested for integrity.

If a pipe passes the air test, it will be watertight as well as airtight. Water, being a larger molecule, requires larger gaps to pass through than air, so anything airtight is automatically able to hold water. It is therefore quicker and easier to run the air test to check each section of a pipe rather than using the water test each time. Only run the water test when the pipe fails an air test.
