NOTE: previously I mentioned a tub basket wrench. I am attaching some illustrations that will help you visualize the steps I outlined. If not, what is the worst that can happen? A bit more water damage to the sheetrock below, but given that you are going to have to cut that sheetrock out to replace any piping anyway, there is no increase in loss. In all likelihood these measures will resolve your problem. If in doubt, regrout the tile and seal the grout or recaulk all seams. Carefully examine tile grout or caulked seams in the shower enclosure. In many cases that problem can be resolved by installing plastic shower guards on both ends of the tub.ħ. After someone takes a shower, check the front apron on the tub and the floor area carefully to see if the tub may be improperly pitched or the shower curtain is not properly keeping the water in the tub. Quite often the spout tips will become corroded and water will cling to the underside of the spout by surface tension, then go down inside the wall. (The o-rings are available at all hardware stores for under $.20 each).ĥ.Carefully examing the tub spout for sings of leaking or corrosion on the underside of the spout pipe. If there is signs of leaks at the base of the stem where it joins the mixer body, you can first try tightening the stem, or you could shut the water off, pull the stem and replace the O-ring gaskets. If you see signs of leaking near the handle stem, the stem packing nuts can usually be tightened a bit to solve the problem. You may see droplets of water or corrosion that would be telltale signs that a leak may exist. Remove the shower/faucett mixer assembly handles and escutcheon tubes, then use a flashlight to visually inspect the valve stem packings or stem to body connection for signs of leaks. in most households today we rarely fill the tub so the likelihood of the overflow leaking is very slim, however, if you do fill the tub occassionally it would time well spent to remove the overflow cover, then carefully work the rubber gasket between the overflow and the backside of the tub out, apply a thin film of silicone on the gasket, then re-insert the gasket and tighten the overflow in place.ģ.Pull the shower arm pipe out of the wall and clean the threads on the end of the pipe, install 3 full wraps of Red Teflon Tape (Red teflon tape is triple density tape which is certified for use on 1/2NPT threads) or pipe dope and re-insert the shower arm and tighten it in place.Ĥ. You can then clean the underside of the tub basket flange, apply plumbers putty or silicone, and tightly reset the tub basket with the basket wrench.Ģ. Once the basket is pulled the rubber gasket that fits between the tub shoe and the underside of the tub can be replaced through the tub drain hole. Using an inexpensive Tub-BAsket Wrench the basket can be pulled. The most common source of a leak under a tub is the tub drain basket. I would begin by addressing the most common sources of tub leaks which can be addressed through non-invasive techniques which will not require opening the walls of ceilings.ġ. When the waste and overflow is in a concealed location we must us a glue in type kit. If your home is plumbed with PVC pipe in the DWV system it is highly unlikely that the Waste & Overflow piping is leaking because the code prohibits using slip joint type waste and overflow kits in concealed locations. There simply are too many variables to begin cutting into ceilings and replacing pipes without taking some simple DIY precautions or further investigative steps. The appearance of a yellowish stain on a ceiling directly below a tub is a strong indicator that there is a minor leak, however it still does not determine if the leak is resulting from a drain leak, a water supply line leak, a leaking mixer valve or shower riser, or even an improperly pitched tub that may allow shower water to run off on the floor, or a bad caulking joint on the tub apron. The word assume can then be broken down to to its root ASS-U&Me and quite often that is the end result, an assumption often proves to make us all look a bit foolish in the end. Meaning no disrespect but the word Assumption is derived from the word ASSUME.
