Sureflo + tubing question

[1-GEN-SAPPER]

I am going to give it a try with a sureflo 2088 pump and 5/16 tubing. My question(s) are 1) I am using 5/16 as a mainline, should I be using 3/16 laterals? 2) can I get by without lateral in general and just run 5/16 from tree to tree and put it my drops along the way? 3) how many taps can I put in each main line of 5/16 without laterals. I have more but let's start there. Thanks everyone in advance. FYI this is all flat land.

When I had a Shurflo setup, I used 5/16 tubing and I had lines that were up to 100' long. I think the 3/16 would be too small. I would just run the 5/16 from tree to tree and add the drop lines in like you said.

Ok sounds good, how many taps were you running on the 100ft line? Thank you for your input.

I use 3/16 on my lines with a surflo and runs of up to 500 feet and they work very well. You need to keep your lines to 30 taps or less but you do not need to worry about proper slope as much as you do with 5/16.

I have run 3/16 for several hundred feet on a shuflo with great results. I am running a 3/16 with 5/16 drops this year with a little better results so far but won't know untill the season is up. I have also run a shurflo on 5/16 with great success. The key to these is zero leaks and they need to be checked often. I can tell by the sap coming out of the pump!p if there are leaks. If the sap spits out of the line into the tank it is probably getting air from a leak. A tight system will give you a stream of sap with pauses here and there. Jeff

If you are using 5/16 as a mainline, you should use 5/16 drops so you can use standard tees. No benefit to using a 3/16 drop. You need to be more careful about pitch and sag if using 5/16 to avoid pump surging. 3/16 is a little more forgiving if you can limit the number of taps per line to 30-40.

Thanks everyone I am going to put everything in the next couple of days and see how it goes. May your sap be overflowing!!

I am contemplating 5/16" on a Shuflo but keep seeing posts about overloading it? Can I zig zag mains from tree to tree (20 taps +/-) then into the pump or is it better to use 5/16" laterals with 5-7 taps per and then into a 5/16" main? Also, if running an in tank recirculator, will that overcome the pitch / sag concerns?

TIA

I would stick with all 3/16 unless you have 30-40 or more taps. Then split them up if more than that and run multiple lines. You can zig zag between trees no problem.

3/16 fills the line and then the vacuum sucks out. Uphill, downhill, whatever. 5/16 doesn't fill a line. It runs along the bottom. As such, it doesn't want to go uphill. The recirculation setup won't help with a sagging 5/16 line. 3/16 has advantages and disadvantages, but forgiveness with slope is a huge advantage. If you have a vacuum pump, you could run the stuff right on the ground if your want to. Or up over trails. Can't do that with 5/16 unless it's down hill the whole way.
