PH and water density/flow?

Do you have a ball valve or a gate valve on your herbie? I understand some ball valves are 'inaccurate' or hard to adjust, and I've heard of valves 'adjusting' themselves under pressure... could be the valve.

Ya forgot to add, got a gate valve. Next step is a flowmeter on the sump return line, see what the pump is acctually pumping up to tank.

It's not a major problem, just gets annoying as every 1-2 days I need to adjust the gate.

OK, I have figured it out. My Mains power fluctuated between 117.3-120.6v throughout the day. I'm on a community grid system, so the more power demand during the day, the lover the voltage. Just enough to cause a little flow variation in my return pump. Now, anyone know of a good power conditioner? I am going to try my UPS, see if its constant, but I think it fluctuates with Mains as well, only switches to battery on power fail....

Need to figure out how to make a auto Buck/Boost transformer

Edit, Nope, My UPS drops from 118 to 108 upon power fail. so it does not actively condition the power

They also make a 1000VA unit that is black and has Home Theater written on it so it costs five times as much.

Way to go Sherlock, excellent deduction, I will have to remember that little tip.
