Shurflo's capabilities

how was your line cut?

[Dale Sparrow]

Guys, I have two lines each 500 feet, with 87 taps on one and 53 on the other, all 5/16 tubing with about 30ft of natural elevation. They are tied together at a 1/2" header. One runs like i expected with gas bubbles and sap. The other no gas bubbles and sap slowly trickles through. It seems like I have an air leak but cant find one anywhere. How can I find it? can I use a compressor at the end of the line and go walk until i find the hiss? or is there another way? idk about to give up

I have seen the same thing, trees gassing causing most of the bubbles.

The line looked like it was cut in the shipping and transit. It was a 1/2" slit lengthwise along the tubing. Does 5" of vacuum at the end of the line, near the pump, sound correct without sap???? Oh by the way, my air tank worked great but because of the leak i ran out of air faster than I ever thought possible. I am looking for a regulator that is affordable to add to the tank for future use...

without water or sap (that doesn't compress) in the line there are a ton of variables to figure if 5" of vacuum is a good sign or a bad sign. Probably have to wait for the sap to run to see the real results. sounds like you're on the right track though.

I would agree with BSD. I just went to using shurflos too and found the same results yesterday. Before the sap started running good, I was only able to get about 5 inches at the pump. Yesterday, when things started to wake up, I achieved 16 inches at the pump. On one end of my lines, the other gauge read 18 ish and another was 23. It appears having sap in the system helps to increase your gauge readings and vac. Now we are in another deep freeze, i'll have to wait to see anything again.

Use a recirculation line out of your tank to keep fluid moving threw the pump. I have one and can get 20+" of vacuum with my Shurflo 4008 and 90 taps.

I have a header shaped like a "T", two incoming lines on both sides. My recirculation line comes into the middle, straight in line with the pump. Everything is valved so that I can troubleshoot and isolate lines. When I run the recirculation line at full speed it sure does pump well, I have to crack the other lines or lose prime because there just hasn't been enough sap. Give me sap...

[awpoolco]

Are we going to get any sap this week????

[awpoolco]

If my shurflo only has 10 in of vacuum before I hooked it up, how is it possible it will ever have more than that after hooking it up?

[Biz]

It will. I have 3 out there, they pull 8-12" with no flow. With sap flow I get 22-26" at the pump. They are not efficient at pumping air, just liquids. Now I am hoping for more liquids
