I have three single handle faucets in this house. The one for the shower works fine. The one for the jacuzzi worked fine when the home was built in 2007 but is now very clogged.
The third one serves a tub/shower has only given hot water since the house was built. I'm hoping the problem is a cartridge installed upside down but when I get a look at the pex feeding it both feed lines are white and I know the standard in this development is blue for cold and white for hot. We have been able to get along without using it or by adding cold water with a bucket, not fun for guests.
If I send pictures of the valve can you tell me the brand and model number? I can see two adjustment screws, one on each sice, and can see that the cartridge is held inby a clip. There is also an adjustment screw on the handle unit.
Where should I send the pictures?
