I wasn't able to properly winterize our unit in time for a very early, very deep and vey unexpected cold snap last September (went to -8C overnight from 20C the previous day
Anyway, as a result, we now have a small leak in our SHURflow pump (model 2088-422-144) right where the pressure sensor mounts to the head of the pump. I've tried a couple of different and creative "field repairs" but to no avail. It still leaks, both when the pump is running and when we are attached to city water. I suspect the culprit is a leaky diaphram on the pressure sensor side but it's possible that more parts were damaged by the freeze - it's hard to tell.
So, do folks feel it's worthwhile just buying a replacement pressure sensor (about $30) or do I need to look at replacing the whole pump ($160)? Any thoughts or experiences?
