The only thing worse than a cold shower is hot water. If there is no cold water in the shower, you have come to the right place. The lack of cold water is usually caused by the failure of the pressure balance valve in the spool. This part is located inside the shower faucet. So, is it convenient for you? With some tools and some patience, you can replace the spool by yourself.
You have a Hot And Cold Faucet, but there is no cold water in the shower
Start troubleshooting by checking other taps around the house. If none of these have cold water, you can start to figure out the problem. Look for shut-off valves in your basement or main water supply line. The valve may have closed unexpectedly. Hope you can reopen the shut-off valve and everything goes well. If this is not a problem, you should call a professional.
If other faucets around the house do have cold water, the problem is most likely the pressure balance valve.
Why is my shower cold?
Is your shower cooler than normal? There are several possible causes of cold showers. The first and easiest thing to check is the other faucets in the house. See if they are rinsed with hot and cold water. If other faucets around the house do have hot and cold water, the problem is likely to be the pressure balance valve in the shower.
Why the balance valve fails
The pressure balance valve can adjust the pressure and the ratio of hot and cold water flowing out of the nozzle. Over time, corrosion and mineral accumulation can damage the cartridges, especially if the faucet is not frequently opened.
It is not difficult to replace the valve core of the faucet, but the faucet needs to be disassembled. The most difficult part of repairing is removing the old ink cartridge. If you are not satisfied with this repair, this is a good time to call a professional. Feel confident? continue reading:
