Hi,
The most common problem with these circulators is that the stator gets stuck and does not turn.
Sometimes you can take out the four bolts on the corners and pull the motor off. Get the stator freed up again and it will work. Make sure to turn the water off before dissassembling the pump. Hopefully you have valves do you can isolate the pump.
Also check that the impeller has not broken off the end of the shaft, that also happens sometimes.
You can check the cap. with an OHM meter by switching the terminals with the test leads and the resistance should count down to zero with each switch of the leads on the terminals...if not it is bad, but replacement of the cap. may not fix the pump usually it is a secondary failure...
If you can't get the pump ot work after taking it apart and making sure it turns freely then I would replace the pump.
Question edited for correct spelling of maker 'Noen' to 'Moen'.
'Fix' as in it is leaking? Or tighten it down because it is wobbly, or something completely different?
Well, we can have a one on one seminar by the internet. I've been a pumpman for 20 years. I can share with you my experience (household pumps, suibmersible pumps, turbine pumps, gear pumps, piston pumps, dewatering pumps, mud pumps, trash pumps, mining pumps, solids handling pump, etc....) Just take your pick. Just send in your e-mail for assistance. God bless.
It is leaking due to a defective mechanical seal. It needs to be replaced. To replace it, is to take the pumpcase off by taking off the bolts that hold it. Then, take the impeller off to take the mechanical seal behind it. Put the replacement in, and reassemble the pump. Just get in touch with us by e-mail to get more assistance.
Move the lever or turn the knob. Check the stop tap under the sink. Make sure the faucet control knob or lever is tight, There is normally a removable cover that hides the screw..
