too many options--help!
« on: February 13, 2013, 09:38:46 AM »
Sir,

My house has roof cistern water, two tanks of 1000 gallons each, above ground, under cover.  I have this pump:http://images.harborfreight.com/manuals/47000-47999/47906.pdf  It's a POS, and I'm half-suspecting the pump quality to be the majority of my problems. (yes, I'm sufficiently embarrassed that I bought a harbor freight pump...).  It sits between the two tanks, so it's technically below the water line.  Home is two story, 1/1, with a propane insta-hot.  And that's why I'm here.  Which valve should I use?  I've only become more confused browsing the site and forum.  I can say, though our water is pure rain, we potentially have issues with algae or slime, although it's never non-potable.  I also have particle, carbon, and UV filtration on the system. 

Thanks in Advance,

Chris and Mary

Any of our 1" valves will work.  That pump is set up at a 20/50 pressure switch going by the info you sent so look at the CSV140 or the CSV1A set at 40 psi.  I know you have storage tanks but what size is your pressure tank?

Karen,

Thanks for the immediate response--I only checked back here to assure the post went on the forum properly!  The pressure tank is the same one in the link--the pump sits atop it; it's five gallons.

as a side bar, can you illustrate for me why one would chose the cvs1a or the cvs140?  They appear completely different in design; what sways one over the other?  I think the 140 is adjustable?

Great...our product works better with smaller tanks.  I chose the CSV140 because your pressure switch shut off is 50 psi.  Your shut off pressure needs to be higher than our valve set pressure.  The CSV1A is adjustable from 15 to 150 psi so it could also be used for this application.  The CSV1A would be best for the above ground type jet pump.
