Last post we provided broad ideas on how to repair a bathroom but today’s post specifically focuses on the shower valve.

Shower valves help in controlling the temperature and flow of water and if the valves have a problem then it leads to leaky showers.

We understand that it is annoying, wasteful and also increases your water bills. Shower valves which leak inside the wall are more concerning as they can cause rot, mould and structural problems.

The common reasons for the valve to leak or slow down the pressure of water are wearing down of inner seals and parts or clogging due to hard water deposits.

The rubber seals which control all this get worn down due to time and use causing the water to drip out!

If your shower faucet is dripping then you don’t need to replace it, it can be repaired single handed with the help of basic tools in less than an hour!
