We have a 3yr old installed bathtub and we have determined by pouring water around the spout and then around the faucet control handle and then around the tub-rim that all three places leak a slow drip. We do an annual inspection, husband goes under house with flashlight and I pour the water over each area mentioned above while sealing off the other ares with duct tape and plastic to determine if we have leaks. This tub has leaked in those 3 areas since it was installed 3 years ago. My husband recaulks it yearly but each year we find that it leaks again in those same areas. Is there a more permanent way to seal around a spout and faucet handle and around the rim of the entire tub to better seal it for a longer amount of time? I was thinking that we could dig out the old caulk around the rim of the tub and put hydraulic cement in the space first, let it dry and then put caulk around the entire rim of the tub. Is this advisable? What more can we do for around the spout and faucet handle other than just caulk? I'm sure most people don't check as often as us, we are quite diligent so there must be something more that we can do to insure that water is not entering our walls around those areas. The pipes do NOT leak. Thanks for any and all advice.
