PartsCompleting the repair requires very few parts. All you need is a new Delta 1400 series faucet valve. This is the one I got and it worked great:
ToolsThe tools that I used to complete the repair were similar to the following. I've chosen tools here that are well-priced but also have a reputation for being good quality, so you get the most value for your money. These are tools you can buy once and use for years and years:
- Picquic Multi-bit Screwdriver
- I've had a Pic Quic screwdriver for years. They are well made and very useful. I use mine almost daily.
- Channellock Tongue and Groove Pliers
- I love my channellock pliers - they're well built and useful in many situations.
- Flex Scraper
- Newborn Brothers Hex Rod Caulk Gun
- Dap Bathroom Silicone Rubber Caulk (White)
StepsTo complete the repair, I took the following steps (as outlined in the video below). For your convenience, I've also produced a printable PDF of these steps.
- Shut off the water supply to the tub/shower.
- Remove the knob center cap.
- Unscrew and remove the knob.
- (optional) Unscrew and remove the backing plate. Only required if you want to re-caulk it.
- Slide off the outside sleeve.
- Remove the brass bonnet.
- Remove the old cartridge.
- Clean any debris from inside pipe.
- Insert new cartridge. The cartridge is marked with "hot side" on the cartridge rim. Insert cartridge so the "hot side" is on the same side as the hot water line (usually left). At this point you may also want to adjust the rotational limit stop (see instructions included with cartridge).
- Thread and tighten the brass bonnet.
- (optional) Clean old calk from backing plate and wall. Only required if you completed step #4.
- Slide outer sleeve back on.
- (optional) Replace the backing plate and screw it in place. Only required if you completed step #4.
- Replace the knob and screw in place.
- Replace the center cap.
- Turn the water supply back on and check for leaks.
- (optional) Re-caulk the backing place if required.
