How to solve the blockage of the shower room outlet pipe

1. It stands to reason that there should be no problem with re-applying silicone for sealing. If you don't destroy the tiles, it seems that there is no other way than glue and seal.

Second, I think the reason for repeated water seepage should be related to the operation of your gluing. 1. First of all, the original sealant should be scraped off before gluing, and the gaps should be cleaned, and it should be fully dried before the next operation; 2. The embedded depth of the sealant should be greater than, but not greater, too thin is not conducive to ensuring the quality of the seal, and too thick is easy to be cracked by cold and hot expansion and contraction; 3. When purchasing sealant, we must pay attention to its guarantee period, and at the same time pay attention to the silicone weather-resistant sealant instead of silicone structural adhesive; 4. After the sealant is filled, the glue seam should be carefully checked, and if there are bubbles, hollows, broken seams, inclusions and other defects, they should be dealt with in time. It is necessary to keep the glue seam full, dense, continuous, uniform and free of bubbles.

If you can pay attention to the above requirements when you inject glue next time, I think there should be no problem, because for your current situation, using silicone sealing is the best, most professional and most feasible choice.

Good luck with a speedy solution!
