Step by Step Guide To Fix The Water Hammer
Gather all the tools and equipment that we have enlisted above. Starting work without buying any one of these can lead you to no-water for a day in your house or leakage afterward. Since other tools can do what the enlisted tools can do, you can use replacements for these tools except the water hammer arrestor, of course!
Find an access panel in your home by which you can access the pipes. Open the access panel cover with a screwdriver, if it is screwed to the wall.
If you hear a bang when abruptly shut the tap, it is most likely that the pipe is not securely fixed to the surface properly. If all your pipes are made of metal, you can just secure the pipe with a firm surface and see whether the sound appears or not.
If the sound remains, you have to use the water hammer arrestor aka shock absorber to completely quiet the pipes. Don’t confuse yourself!
Now, the main task! Turn off all the water outlets and drain down the water tank. This is necessary because you are going to cut the pipe in the next step.
Generally, water hammer arrestors are installed by T-fittings. So, you need to install the T-fittings into the pipe and then attach the shock absorber with it.
So, measure the T-fittings and cut the pipe in such a way where you will have enough room to insert the pipe into the T-fittings from both ends.
So, the cut needs to be smaller than the size of the t-fittings.
(Please remember that some shock absorbers do not need T-fittings. So, check the one you bought before installing a T-fittings.)
