Exactly how do I change a washer/cartridge (I suppose this is what needs to be done!) in a Lahara tub faucet. We are beginning to lose a lot of water through the continuing drip. Thank you for any advice.
Thank you for your question. Based on your description, If your faucet is just dripping from the spout, then I would suggest replacing the RP46073 adapter seals. If the leak persists, then the RP46463 cartridge assembly will need to be replaced.
Once you have the new parts, you can follow these steps below to repair your shower faucet. Before you begin, make sure that you first shut off the faucet's water supply.
1. Remove the handle. First, remove the temperature control knob cover. Depending on when your faucet was manufactured, the cover will be removed in one of two ways. You will be able to either "pop" it off of the temperature control knob by prying it off with a small screwdriver, or you will be able to slide it downward, in the opposite direction of the "pointed" end of the cover. Once the cover has been removed, you will be able to see the temperature control knob. It is held on with a screw. Unscrew the screw to remove the temperature control knob. You can then slide off the volume handle and trim sleeve.
2. You should now be able to see the bonnet. This is a round brass nut. You should be able to unscrew the bonnet by turning it counterclockwise by hand. If it has never before been removed, it may be very tight, however. Wrap a cloth around it to protect the finish and use a pair of channel locks to give you some extra leverage. Be careful that the entire valve does not start to turn as you are trying to unscrew the bonnet. This will break the copper supply tubes behind the valve, which will require the faucet to be replaced.
3. Once the bonnet has been removed, you can grasp the cartridge stem (to which the handle was attached) and pull the cartridge assembly straight out of the brass valve body.
4. You will then see the old adapter assembly. Remove the Phillips head screw and remove the old adapter assembly.
5. Turn both the hot and cold water back on for 5 to 10 seconds to flush out the valve body.
6. Slide new adapter assembly in place and tighten up the Phillips head screw. Remove the black plastic holder for the adapter assembly.
7. Reinstall the cartridge, screw the bonnet back into place, and reattach the handle and other trim components. You can now turn the water supply on and test your faucet.
