Shower faucet repair can be a pretty simple do it yourself project. But there are a few surprises for the inexperienced. Shower valves come in a lot of different shapes and sizes but the newer models are pretty straight forward. Let’s explore some of the most common brands.
Shower Faucet Repair – Delta
Delta shower faucets are one of the best value faucets you can buy. They are designed simply. The parts are easily found. And they come with a lifetime warranty. Just be careful how you treat the faucet finish. They don’t usually cover the faucet finish on the warranty.
Older Model Delta Monitor Shower Faucet Repair
Before beginning any shower faucet repair I confirm the brand and model. Then I purchase all parts necessary for the job. If I’m unable to identify the model of the shower faucet I’ll take the old cartridge out and have a plumbing supply sales person identify it for me. It’s always a good idea to take a picture of the faucet handle and trim with you.
The older model Delta Monitor shower faucets were very well made and easily repaired. But they had, in my opinion, one major flaw. The faucet is constructed of two heavy brass sections connected by three soft copper tubes. So, if the bonnet nut seized, which it does often, an impatient or inexperienced person can break the valve and shut the home water system down until the faucet is replaced.
Step by Step
Now let’s break down each step of the repair.
- Identify the brand and model. Then purchase a complete rebuild kit or cartridge.
- Shut off the home water system at the entrance valve or water meter.
- Drain the water system by turning on and leaving on a outside wall hydrant or lower level faucet. Then turn on the shower faucet you’re repairing.
- Remove the handle. Your handle could be crystal with an index button in the middle covering a set screw or a brass lever with a set screw.
- Then unscrew the bonnet nut. If it’s seized lubricate it with penetrating oil or WD40 and let it set for 10 or 15 minutes and try again. This may take a couple of attempts. If it still won’t budge, stop and call a professional.
- Remove the cam and ball assembly. That’s the stuff under the bonnet.
- Then, using a small pick or tweezers, remove the rubber seats and springs inside the faucet housing.
- Inspect the inside of the faucet housing for calcium build up or cracks. To remove calcium, gently pick at it with a wire brush or small pick. Be careful not to score the brass.
- Lubricate the new rubber seats with plumbers grease or vegetable oil. Don’t use petroleum jelly.
- Insert the springs into the rubber seats small side in.
- Slide a small pick or screwdriver inside the rubber seat and spring and insert it gently back into the faucet housing. You may need to work at the seat with your finger to get it to go all the way in.
- Lubricate the ball assembly and insert it into the faucet housing. There may be a small tab inside the faucet housing that accepts a slot in the ball assembly for proper alignment.
- Place the cam on top of the ball assembly with the little tab on the side fully inserted into the slot of the faucet housing on the side.
- Thread the bonnet back on while holding the cam down with your finger.
- Reinstall the handle.
- Shut off all faucets. Turn on one tub faucet on the top floor of your home.
- Turn the water to your home on about a third of the way to allow it to slowly fill the pipes. Don’t rush this. You want all the air to escape through the top tub faucet. But you don’t want to stir up too much calcium debris inside the piping that could clog faucets.
- Once the tub no longer has any air coming out, shut it off.
- Purge all other interior faucets of air starting on the top floor and beginning with tub and shower faucets. Then purge sink faucets. And finally flush toilets.
- The last step is to purge the lower level home plumbing fixtures and test your shower faucet repair for leaks.
