I get only hot water from shower

SOURCE: When turning on the hot water on dedicated hot

Pull apart the front of the valve and there is a limiter that is set to limit hte hot water, you need to adjust that limiter. I find many valves are shipped with teh setting too cold.

Behind the handle check to see if it has a dail to take out and replace at a different postion this will change the hot and cold. It a anti scald protection device. Don't remove cartridge just adjust dail.

Mark where you start and take out and move a 1/8-1/4 turn at a time and replace til temp desired. It has teeth like a gear you move to adjust temp.

well they should be same size but unless you getting more of one then other then sound like mixing valve is not mixing. do have 3/4 hook up to mixing valve? you only need 1/2" to valve.

Hello. It sounds like your plumbing was installed wrong, with the hot and the cold supply lines reversed. If that is the case, those supply lines will have to be replumbed to make your faucet work properly. Often, if those lines are accessable, it is only a 20 minute job. Joe
