How to Fix a Shower Diverter
Repairing a Leaking Shower Diverter
In case of water leakage, here is how to fix a shower diverter in a wall:
Shut off Water Supply
To shut off the water supply, find the main and branch shower valves. Use your wrench to turn the handle clockwise.
Unscrew the Faucet
First, the tub faucet handle and decor plate must be unscrewed. They are located on the front side of the tub faucet.
Now, insert a screwdriver into the hole located on the end of the handle. Then turn the screwdriver counterclockwise until the set screw is loose. Simply lift the handle down and twist the decor plate off.
Clean the Insides of the Faucet
Mineral build-up around and inside the faucet might be causing it to leak. After unscrewing it, look for debris lodged inside it. Use a file or screwdriver to scrape off the grime. If you can’t clean it, soak the faucet in vinegar overnight and clean it easily the next day.
Check the Flapper
Check the condition of the rubber flapper. With time, it can begin to rot, causing water leakage. If the flapper is rotten, replace it with a new one.
Reinstall the Items
Reinstall the bathroom decor plate and faucet handle. Then, reconnect the hose and briefly test the shower diverter.
Fixing No or Low Water Pressure in a Bathtub Diverter
If you’re experiencing low or inconsistent water pressure in your diverter, here are the steps explaining how to fix a bath shower diverter with a lever design:
Remove Bathtub Spout
Remove the bathtub spout. Then, remove the back cover using a flathead screwdriver and find the diverter gate.
Clean the Insides
After cleaning the insides of the diverter, the water pressure usually returns to normal. Use a filer or screwdriver to scrape off the grime.
Analyze Gate’s Condition
If the gate is bent, replace it with a new diverter. Also, use the plumber’s putty on the edges of the sink and countertop.
Reinstall Tub Spout
Once you’ve reinstall the tub spout, pull the diverter lever rod up and down to check.
Check If It’s Working
The lever rod may be detached inside the hose wall. If it still doesn't work, a professional can help fix it.
