Common Leaks and How to Fix Them – Part 3

Common Leaks and How to Fix Them – Part 3

Following on from last week’s article regarding leeks caused by damaged grout, part three looks at something I come across all the time in Edinburgh. A leak from under the bath or shower where the bath/shower waste joins the appliance.

Bath/Shower Waste Leaks

When this is firstly installed silicone sealant is applied both top under the chrome section and below where the washer and hex nut join to the bath. Over time small amounts of movement and silicone wearing away becoming mouldy can and does account for so many leaks I’ve seen over the years.

Heres how to fix it:

You will find a screw in the middle of the plug, locate this and slowly unscrew the screw until all way out. This will separate the part that screws into the trap and the chrome section on top. Unscrew trap oof the bottom part and then un do the hex nut that seals it to bath tub or in case of shower screw the lower part of trap off. Then take out both top bit, bottom bit and the rubber washers usually one on top and one under on bottom. Clean off all silicone with silicone remover or Stanley blade. Now you’re ready to fit it all back together rendering it leak free.

So firstly apply a small bead to the white ceramic/cast steel part of tub/shower around the top where plug hole is, second drop through the top chrome bit with washer under it to top part of plug hole. Third, locate bottom of chrome bit under bath, take the bottom section of shower trap or bath waste with overflow and apply thin bead of silicone around the washer that will be forming a seal under the bath (not needed for shower trap). Now screw the bottom of chrome section into the black plastic section using the large screw you took out earlier, tighten up just beyond hand tight.

At this point silicone may leak out sides as tighten so lick your finger and smooth it round the connection. Link up the bath trap to the black plastic section and screw up tightly. Test with both running taps and filling bath full with plug hole in place to see if holds water without leaking.

To sum this all up I would say that, all these three leaks can be easily prevented by keeping an eye on your grout and sealant condition. Obviously blackness is an obvious sign to be aware of and to think about taking action before leaks occur, because they will. I really hope I’ve managed to save some people some money and prevented any further damage to there homes.
