Best bet would be to just get a Watts repair kit and install it, either
by yourself or get a buddy to do it. That'll giet you like new pweformance.
It really doesn't take plumbing skills to do that, no soldering required.
I've had to put a replacement kit in the one in our house a couple of
times in the last 25 years when the thermostat inside gave out.
Look on Pg. 33 of this file:

The repair kits are available at most any plumbing supply store. The
last one I got came from Home Depot IIRC.
Good luck,
Jeff
