Re: Entropy

Inspect closely the O ring for scratch or pinch that could damage its "skin". As you probably are aware of, O ring seals are mostly excellent, but ask for perfect race surfaces. I would not expect good result adding some paste or sealant. I might add some lubricant, as long as it is safe on rubbers ...

Re: Entropy

Well, you'll have a spare 1/2 HP pump.
May be more reliable than brand new, new stuff.
I like old stuff I repair, rather than today's junk.

Can we have a picture of the hairline crack ?

Re: Entropy

Next I will run these through the washing machine and see what happens... When I run out of patches this experiment will be over... I started with 20 patches but I am now down to only a handful.

Re: Gentle persuasion over time

My heat pump works much better with 30's outdoors than teens. JR That is the big trouble with air air heat pumps, the efficiency drops at lower air temperature. That is a bit paradoxical, it is good when it is not so cold outside. It is even worse, at very low temperatures; The outdoor heat exchang...
