Shurflo vac.

[Dale Sparrow]

I am running 6 pumps, two 4048 pumps, one 4148 (Aqua King 2), one 4248(Power Blaster 2) and two jabsco v flo 5.0. All seem to work about the same. 430 taps total, all pumps pulling on 60-85 taps each. With very little flow they get 16 in of vac, with a good flow they get 23-25. Five 0f the runs are on an incline and are getting 26-29 in at the top of the run, all on 5/16 no main lines. The most taps I have running trough a single 5/16 line is 52. I had a run that had 70 taps on a single line but vac at top of hill was same as at pump so I added another line starting from the middle of the hill to the pump. Much better, now getting higher vac at the top of the hill. Optimum number on 5/16 for some natural vacuum seems to be 35-50 taps.

I get between 4 and 7 inches of vacuum on 5/16 with 34 and 44 taps on two lines. But that is with a pretty decent slope.

How do you like the 3/16?

I run a 2088 on 3, 3/4 main lines and 3/16 laterals all new this year. They come into a manifold together with a recirc line. About 175 taps. When it's running hard it get about 18" and never goes below 10".
