A leaky shower drain is certainly upsetting and may prove to be a day spoiler. There can be various reasons for your leaking shower drain. The most common reason is a crack in it.
Repairing a Leaking Shower Drain
After the checklist of what we need for repairing a shower drain, let's take a look as to how to go about this plumbing problem.
After confirming that the drain is actually leaking, the next task is to create an access panel to reach the shower. To do that, you need to go where your shower drain is located and check out the pipes leading to the shower. They will most probably be under the flooring or above the ceiling in the floor beneath the drain.
Now that you have found out where the pipes are, you need to keep a drop cloth or a pan beneath the spot of the drain on the floor. That will catch any water which may leak out when you cut an access to the drain.
The trick here is that you have to remove that piece very carefully, as it has to be placed back in its original place once you are done with the repair. Your access to the pipe may be through a closet, bedroom, or even an attic.
This is a very important part of repairing your shower drain leak. Here you have to find the source of the shower leak. Normally, there is a prominent discoloration or dripping at the spot of the leakage.
After you are done with the earlier step, you would know whether the drain needs to be replaced or just a patch would do. You will find vital information related to this in the repair kit.
The instructions will guide you in dismantling and reassembling your shower drain. Fix the broken part of the drain and if all the pieces fit together, use a combination of the old and new. In this manner, reassemble the drain and then affirm that all the pieces of the drain are properly in place.
Now the last thing to be done is to check if the repair has turned out to be proper. For that you have to turn on the water in a small stream and check the pipe which is downstairs for any leaks which may have developed even after replacing the strainer, gasket, and so on.
In case of no leaks, patch the wall with drywall mud and mud knife. At the same time you also should remember to cut away and remove any piece of ceiling having watermark damage from the leak. To replace that necessary portion of the ceiling, use drywall.
