View Full Version : Recommendations on 3/16 manifold setups for shurflo pump?

Hi all, I'm in the thick of it now...I've got my ShurFlo pump on solar battery charge and now need to connect 3 (and maybe later 4) lines of 3/16 to the 3/8 tubing to my pump. Any recommendations on a good way to setup this manifold?

I was looking at something like this as a possibility after discovering my barb-fitting adapters are not actually the correct size:

I go 1/2" to the pump, then use a 3 or 6-way star fitting. They're 5/16, but then it's 5/16 tubing to a valve so I can close down a line, then the other side of the valve can be a 3/16 barb. Can also put a 5/16 quick connect fitting in between the star and the valve.

Star fitting is then a yearly replacement item. Cleaning them (or any manifold) is a pain.

Checkout this manifold that AlRock shared on this thread (http://mapletrader.com/community/showthread.php?38403-5-16-Shurflo-with-a-manifold):

Eventually I want to shoot for something like that, but in the mean time I'm working on a setup similar to what DRoseum has here (https://youtu.be/XqPVJtPYBlo?si=isuvcZuHVpb3xoTp&t=11)

I did some thing like the FB post but used a 4" PVC pipe. Put it vertical. Drilled and threaded the barbs into it. Worked great for me last year. I also put quick disconnect on the lines going into it.

I just built mini-version of the clear PVC manifold from FB. https://imgur.com/a/DpLXHVo

The biggest pain was getting a clean hole to tap for the 1/4 NPT tap. I ended up trying 4 different bits until i found one that didn't chip or tear out the hole. I also tried a few different liquid pipe dopes and ultimately settled on true-blu which actually hardens up a bit.

I made a clear manifold like that and used it for a couple years and then chucked it. Gets funky quickly. The novelty of seeing sap flow in is fun, until it hazes up with goop during a warm spell.

hmm, I was worried about that. I added a screw cap on one end to hopefully allow for cleaning, but I wouldn't be surprised if sealing that becomes an issue.

I had the same; that sealed fine. The tapped threads for the fittings definitely were the worst spot for leaks.

Nice, this looks good!

Just sharing a quick update, I tapped in my little shurflo system and manifold this weekend, it's flowing pretty good:
