recently bought a house and i have come up against my first conundrum. i am hoping to get some clarity via toh users' wisdom.
okay. here is the problem. i have no idea how the water is getting to the ground floor. the shower only leaks when there is someone taking a shower.
i have ran multiple tests, only running the bath faucet, filling up the tub (so i know that it is not the floor drain. running the shower into a bucket (so i am pretty sure it is not the supply line leading up to the shower head, by the way i have no access panel) pouring water onto the walls and floor to see if water was getting in through cracks in the grout/tile. no water appeared after this test. but my only idea is that it is leaking through the tile or grout somehow.
i ran a caulk line around the tub because before there was only a shoddy grout line with a few cracks. i bought a silicone grout to plug up any holes that were in the grout. and yet i am still getting water downstairs. the tile i have is indian slate with fairly thick grout lines (1/8" to 1/4" thick or so)
i am completely baffled. please offer me your advice/theories.
if i were to cave in and call a professional should i call a plumber or someone more general like a handyman or contractor. because i am pretty sure that the leak is not coming from the pipes. do plumbers deal with all things water/bathroom?
