no luck
As far as which side either valve is on, I can't tell. Would the manual shutoff valve be on the supply or return from the tank? I would guess the return (the supply to the faucets). I am kind of baffled that there is only one entry/exit from the tank itself, how does this work? By the way, I have a cistern, not a well. I am able to pull the pump all the way out and look at it, and everything inside the cistern is visible, if that helps at all.
Here's the deal now: Still very low pressure to the shower head and to the kitchen. The only other faucet right now is the sink in the bathroom, and this one seems fine, although I don't know if it is maybe because it is a smaller faucet with a smaller stream? I have pulled the pump out and checked the screen filter around it, nothing is clogging it. We had good pressure for a few days from the kitchen sink, but it has gone down again and the screen at the tip of the faucet has been cleared out. The pressure switch has not tripped since my last post, not sure what is going on with that. However, what baffles me is that this lack of pressure is for both cold and hot water, it doesnt make a difference either way. If there were a problem with the tubing or the pressure tank, wouldn't it only affect the cold? Is the hot water heater its own seperate pressure tank?
I know this is starting to sound crazy, but I can't pinpoint this problem. Like I said, this only started when our power started going out and has stayed consistently low since. I have watched the gauge on the tank and it seems fine. I cannot find any filters at all to check. I found debree on the screen of the faucet, which leads me to believe there are no filters. The pump looks to be a 60/30 (or maybe it was 60/40). I believe we have water with a high iron content, but we have all new faucets, eliminating the possibility of a buildup somewhere.
Thanks for everyone's help, and I guess these are sounding like some wierd symptoms, but any other advice you can give me would be greatly appreciated!
