Question about shurflo 3/16 setup

[ADK_XJ]

After setting up my full, new section of 3/16" to my collection point I think it may need some mechanical advantage after all...i think i have the fittings from my RO build to make a 1/4" manifold for my 3 lines (25-30 taps each) into an extra shurflo pump but my question is this: will 1/4" limit the flow too much on heavy runs or will the action of the pump offset?

Might be ok but thats a lot of fluid for pretty small tubing.
I'd recommend that you use 1/4 to 3/8 tees to reduce friction losses of the small tube. I have 2 vacuum setups that use these and I have been VERY happy with their performance. I use barb fittings to feed the 3/16 line into 1/4 ball valves (so it's easy to isolate lines / check for leaks). Those ball valves feed into the 1/4 to 3/8 tees and then that 3/8 tube feeds into the pump strainer and pump.

So, I had actually watched your YouTube video before posting this (nicely done, btw) but still had some questions if you don't mind...

- what was your approximate all in cost (if you have it) for the components of your setup? I have a pump which should be one of the main expenses aside from batteries and a solar array, I would assume.

- does your setup require any kind of soldering or are those temperature sensors just plug and play into the controller?

- can you explain how the check-valve bypass works in a bit greater detail? I am apparently a bit daft and can't quite follow the diagram.

Thanks for sharing your knowledge!

Thank you - glad the videos are helpful.

All in cost is probably around $150 or so. The shurflo one I built was a tad cheaper than the aquatec one (pump costs and I slightly simplified things).

The w1209 temperature controllers do not require soldering. The probes plug in and there are terminals for power and control output from the onboard relay. There are pdfs online that show how to wire amd program the settings

The check valve is on a bypass loop around the pump (tee off before pump, check valve, tee back to pump outlet). This allows flow past the pump when the pump is off or has failed, yet does not allow for loss of vacuum or backflow because of the check valve.

It has a crack pressure of 0.3 psi which equates to about 8.3 inches of water, which you should easily have in drop towards the end of your tubing setup.

Electricity (along with plumbing) is one DIY arena I'm not particularly good with but I am going to give it a shot!

That price does not include batteries or solar. Mine is run off normal residential power.
