Q: I live in a 15-year-old house where the master bath shower only produces hot water if you first turn on the cold water in the bathtub and let it run for a little while. Itβs always been a problem since we bought the house nine months ago, but now it seems to be getting worse.
A:Β If you get plenty of hot water coming out of other faucets in the house, then there is probably something wrong with the valve pressure in your shower. Itβs possible to fix this type of problem yourself if an O-ring or washer has worn out. You need to shut off the water and pull the valve cover plate to see whatβs going on underneath.
Take a photo of the area and take it to a plumbing supply house to show to them. They may be able to tell you what to do next and what parts you will need. Take note of the brand of the valve so the store clerk will know what you have.
