How small is too small of a tank with a Cycle Stop Valve?
The tank-tee on my 10 year old Amtrol WX-350 sprung a leak. I called the well company who drilled the well and provided the tank. I have a 1 1/2 HP Redjacket pump submersed at 80ft, producing about 25GPM at 60PSI (I believe these numbers are correct). The system was designed to handle running irrigation sprinklers w/o cycling for hours at a time, and not affecting water use inside the house.
The well company recommends adding a Constant Pressure Valve/Cycle Stop Valve (he says they terms are interchangeable), and dropping down to a WX-202 or larger tank (up to a WX-240). Going from a 35 gal drawdown to 5 gal makes me nervous, though everything I read on this forum says small tanks are better with CSV. I was going to step up to the WX-203, but saw a thread with said, bad tank, get a WX-205, which makes sense to me.
I called Amtrol tech support, and they said my old tank has a cast iron tee, which cannot be repaired, but could be replaced, if I was fortunate enough (highly unlikely) to be able to unthread it without torquing the inner copper fittings. I guess the newer ones use SS. He said that my current tank is already too small to allow my pump to run for 2 minute cycles (25gpm@60psi), and that a CSV would help with a smaller tank, when running water for several minutes, such as a shower, but won't help much for the occasional drink of water, washing of hands, or flushing a toilet, where only a small burst of water is required.
Let's say I get a WM-250 (13 gal draw down), if the pump fills up the tank in 30 seconds, and I am not pulling any more water, it will stop far short of the 2 minute minimum recommended cycle run, leading to an early pump death, right?
He also confirmed that a Well-X-Trol is a Well-X-Trol, regardless of where I buy it.
1. What size tank can I realistically expect to use with this sized pump?
2. Will the CSV1W work for me, or must I step up to the CSV2W? If the 1 series is okay, what is the advantage of the CSV1Z?
Thanks,
