This thing has been driving me crazy. It's fine... then I go away and my wife tries to heat the spa and.. it's not fine. I am starting to think it's personal. Like CHRISTINE the killer car.
argh.
So we have a properly functioning pool system (it seems) in all other ways. Diatomacious earth filter gets semi-annual re-do... and shows 10-20 psi after a top bleed consistently. Pumps work perfectly, automation switches are good and the servos to change pool-spa-pool are good.
The heater shows LOW PRESSURE sometimes and there doesn't seem to be rhyme nor reason to it.
It's also home to a bunch of nasty black widow spiders, so I wouldn't mind if the thing just exploded in general.
But... I should probably just fix it. I've no training in this or hvac etc, but I restore and build custom/vintage motorcycles so I know how to spin a wrench. My gut says it's a wonky pressure switch (where would that be located?) and... anyone have a quick and dirty way to use an ohmmeter to find out if this one is copacetic or not?
