Can a water leak behind a shower be fixed without tearing out the wall?

No, you must expose the leak and usually the only way is taking off the wall covering. Not a huge job.


How do you find a water leak?

Water leaks can be tricky. If water is visible on a wall then it could be necessary to cut into the wall to find a leak. Listening in a very quiet house may allow you to hear a spraying leak. If a leak is suspected because of a high water bill, look at the water meter. The small dial moves when water runs. Shut off cut offs under the sinks and toilets and the water should stop running. Turn them on one at a time and watch until the meter tons again. There is your leak.


How do you detect if it is a slab leak?

First, you need to determine if you have a leak anywhere in your home. Check to make sure that your faucets, toilets, showers, hoses, ice-makers etc are not using water. Once you have determined that nothing visible is leaking, look at the water meter. The leak Indicator is a small triangle or star on the face of the meter, and if it is moving, even slowly, you have a leak somewhere. If you turn of the shut-off valve (often near the ground in a closet or near the hot water heater) to close it, and the leak indicator stops, then the leak is on a supply line to a fixture in your home. The shut-off valve often appears to go nowhere. It comes out of the wall, an perhaps splits off prior to going straight back into the wall or slab floor. If the leak indicator does not stop when you close the shut-off valve, the leak is on the service line into your home, and may or may not be under your slab, but is definitely under the ground. Movement on the leak indicator usually means a good deal of water is leaking, and you should see water coming from a wall or perhaps out of the floor. If you have no visible water, and constant movement on the indicator, a slab leak is a good bet. A leak detection company can help you find it, and get it repaired.

How do you fix a leak in the wall that is directly beside your bath tub and may be coming from the faucet in the tub?

Small bit of demolition may be required. Take the tap trim off the tap and see if you can definitely see water coming from behind the wall. The water may only leak when you have the taps on so try that too. Once you have seen the water coming out from behind the wall, you will have to remove the wall and expose the breeching piece, copper and brass assembly behind the wall and repair it by brazing it or get a plumber in to repair or replace.


Where is the water leak when a portion of the base of my wooden cabinetry bathroom vanity is soaking wet yet the inside of the cabinet is completely dry?

Check for a leak at the wax ring of the toilet. This leak will migrate out, on the surface or under the surface of the floor. Check for a leak in the wall in the back of the vanity (the vanity may have to be removed). A slow leak in a wall is likely to be the DWV system, not water.

Sounds like you have a water leak somewhere. It could be from a roof leak, or maybe an upstairs commode, or maybe a water pipe, in your wall, broke.


Why does water leak behind the wall when the shower stem is pulled up but not when it is down and the water is running?

When you pull the stem up, it diverts the water from the tub spout to the shower head. Somewhere between the valve connection and shower head arm, you have a leak. The easiest part to check would be the arm that comes out of the wall that you screw the shower head on to. It is normally screwed in to a "shower Ell" and that connection and or pipe is easy to crack if someone pulls on the shower head. Pull the escutcheon plate towards the shower head and try to see into the hole and look for water at the connection. It would only leak when you are using the shower. If it is another connection or the riser pipe itself, you'll have to access it through the wall, hopefully from a room on the opposite side of the wall. Good Luck


How do you find out where the water leak is coming from when you turn your bathtub water on upstairs?

I would first pour several buckets of water down the drain without running the tub faucet to see if the drain is leaking. Then I would with a spray bottle direct water around the drain lever/overflow plate, tub spout and valve to see if that is where the leak is. I would then move to the valve itself to see if that is leaking checking packings and the diverter. If nothing shows at that point check tub tiling and possible water spilling on the floor. If water is appearing and you cannot determine where it is coming from you may have to open a wall or ceiling to determine. I also try measuring where the leak is and comparing the measurements to locations of tub parts. In any case I try my best to find the cause before cutting walls and ceilings unless the ceiling is already shot from the leak then open it up and look. Wall openings are done on the wall behind the tub valve usually a closet or bedroom wall, never break out the tub wall around the valve.
