Title: Using CSV1's in parallel.
Post by: speedbump on April 04, 2007, 10:03:17 AM

Since most jet pumps are tapped 1" on the discharge and a 1, 1.5hp can do in some cases better than 25 gpm, would it be better to use the 1-1/4" valve or use two CSV1's in parallel.  Not only for ease of not bushing up and down and making it look like an abortion.  But for the lack of pressure losses etc?

The CSV1.25 will basically do the same as two of the CSV1 valves in parallel.  I have had customers who used as many as four of the CSV1 valves in parallel for 100 GPM pumps.  They work great this way as long as you can get them installed without bending them or getting them in a bind.  Manifolding two or more valves together, it is just hard to keep them square or plumb.

Does the CSV1-1/4" have the same 1 gpm fill rate to the tank as the CSV1?

The CSV1.25 has about a 2.5 GPM minimum.  So if you use two of the CSV1's in parallel, you have about a 2 GPM minimum.  Four in parallel would give you a 4 GPM minimum and so on.

Ok, gotcha.

That answers that question.  Be prepared for many more.
