My shower faucet has always been tight but now it has seized. We have only had it two weeks. What can I do!

It depends what you're talking about here. Is this a shower?

The water is heated either by the boiler or an electric shower. Make sure the shower or faucet is receiving hot water. If it is receiving hot water, then the problem is with the thermostatic mixing cartridge. It has probably seized up inside with calcium, so your best bet is to just replace it.

I think it needs maintenance. But this is a job you should leave to a tech. call plumber or goto the store who installed the valve.

The dripping is most likely the water draining back down from the shower riser. Is the diverter button popping back out when the water is shut off?

Good Afternoon, GWBreish:

If the 'seize' is from hard water (white or green deposits on the fixture) a towel or sponge soaked in vinegar or CLR van be tied or velcro bagged onto the fixture for 15 to 30 minutes, then the residue attacked with a scrubber or steel wool pad. If the seize in inside the fixture, you will have unscrew the face plats and paint or swab CLR or vinegar to the meshed parts of the handle.

Our Moen always dribbled a little since the diverter is metal-to-metal and doesn't really have any seal. The loss shouldn't be a stream though.

Check these items:

1. If you installed new faucet seats, did you add a little pipe joint compound to the threads before installing them?

2. Make sure the shower diverter is in the off position and you're not seeing water leaking from the spout that could be coming from the shower pipe or residual water from the shower head.

3. Make sure you have the correct faucet washers - some or tapered and some are flat and must fit the stem counter bore correctly and that the counter bore isn't damaged or the stem shaft isn't bent. Make sure the waskers are the correct hardness.

4. Make sure the screws that secure the faucet washers are tight, but not too tight. It doesn't hurt to add a little pipe joint compound to the screws.

hi, there is a lock nut that holds the cartridge in this will need to be unscrewed, if you have already done that it should only be a matter of pulling it straight out, sometimes the cartridge gets seized in the body of the tap use mutli grips or pliers to pull it out by the shaft that the handle goes on

Hi,
many times the handles will corrode on tightly....
A sharp rap from a rubber mallet will sometimes work, but most of the time you will ruin the faucet when getting the handle off...

If your tub spout has a knob that you lift to divert the water to the waterpic then replace it with a Delta service part #RP17453 pull down spout. It always sends 100% of the water to the shower head and will always snug tight to the wall.

Single handle shower controls always have some water trapped inside. It has probably freeze damaged the cartridge
