Bathtub Faucet Leaking Hot Water: How to Repair It

• Remove the faucet’s handle screw, wiggle and pull out the handle of the faucet. Be careful not to break it if it is stuck. With a hairdryer heat the handle so that it can come off easily.

• Next, remove the stem by sliding the batch socket onto the stem bonnet and turn it anticlockwise to loosen the stem. Use a
sufficient amount of penetrating lubricant and unscrew the stem to remove it.

Have New Replacement Parts

• When going to get new replacement parts, make sure you have already disassembled the leaking faucet and take it with you to the hardware store or plumbing parts distributor in your area.

Replace the Stem Parts

• Unscrew the packing nut then twist the stem in a clockwise direction to remove it from the bonnet. Remove the old packing washer from the stem using a small flat-blade screwdriver.

• Apply the plumber’s grease on the stem threads and put the stem back into the bonnet.

• Remove the screw from the old seat washer and discard the seat washer. To the new seat washer, apply the plumber’s grease and reinstall it.

• Pull out the old bonnet washer, apply the plumber’s grease to the new bonnet washer and fit it in place. Apply a pipe joint compound to the bonnet threads and fix it into the hot water faucet’s body.

• Grease the splines in the handle then reinstall the escutcheon and the handle.
Sometimes, the water corrodes the valve and rust correct on the faucet. You will have to replace the whole hot water faucet.
