I currently have 119 taps and use a MES 4x40 membrane. I couldn't imagine using something smaller.

I had this happen a few years ago, but this year I haven't had a tap pop out despite some cold snaps.

My sugar content (this far) has also been uncharacteristically high (all reds). I'll take it!

I'm curious what pressure switch you are using. I made and sell a device that controls an RO pump (my motive for creating it was to allow for unattended recirculating, but it works for folks that...

I was just going to post the same thing, and Aquatech wouldn't work well with a single 4x40 membrane! I would go with a Procon pump.

I made a device that will turn it off RO when the flow rate drops (or stop) on the permeate line, but I have heard of folks using those outlets and aiming a webcam at the tubing to shut it off...

Not only that, but the forecast for those warm days keeps trending down, so I doubt they'll wind up running at all. Hopefully some snow will melt and I can run my lines next weekend.

I'd liked to have run my lines by now, but instead I'll get some cardio in! I'll probably decide Monday if I'm tapping. If it looks like another deep freeze is coming after this warm-up then I'll...

At a minimum you should be looking at a 4x40" membrane, maybe multiple. I second what ecobeck said, the setup you listed won't make a dent. An Aquatec pump is massively undersized for 4 400 GPD...

Awesome, thanks for sharing what they said. That explains the "no warranty" part! Remoco make a "Fatboy" that's 7 GPM (vs 5.3), I wonder if it would work even better (5538-2E1-69C or 5518-2E1-69C).

Looking at the picture on CDL's site, this appears to be using a Remco 5517-1E1-65C. Oddly, in one spec sheet it says it's not to be used for potable water...

Ideally, the pump is as low as possible.

Thanks! Do you mean videos on how to build the devices themselves, or how to wire these up? I designed and made circuit boards for most of these devices and then assemble the components (Here's an...

Some people let membranes sit in sap all summer, so you could clean and reuse the old membranes if you wanted. I would run some clean water through them, then do a wash or two with RO soap. They...

I had a Seaflo (a knock off Shurflo) pump that didn't last me a year. Towards the end of the season my sap numbers were dropping and I thought my tap holes were just closing up. Turns out the pump...

Why not run the pump overnight?

After making my barometric pressure compensating temperature probes earlier in the year to calculate the brix of boiling sap, I took some time to create two more devices. The first is for those that...

I know a few people that aim a camera at their setup and use smart switches to monitor things while at work. It's a simple way to use ubiquitous technology.

I don't have any need for a remote monitoring setup, but I'm stunned by what they sell for versus what they'd take to make!

I actually got into making maple syrup because I had most of the equipment from making beer! I almost went with a PID controller for an electric brewing setup, but went with a software PID instead...

I actually hadn't considered it (like making maple, this is a hobby for me), but will definitely look into it. Thanks for mentioning it.

A couple of folks reached out asking if I am selling...

This is probably a bit different than the normal homemade devices folks post about here. I'm a big fan of automation, and based on the feedback I’ve received from others I’ve begun creating some of...

I got 107 taps in today. I'm not expecting much tomorrow (a cloudy 37 won't thaw out anything), but I am hopeful the season will kick-off on Tuesday!

Thanks for the replies, I'm somewhat stunned there's not a known formula for this. I am thinking I need to go back to my high school chemistry to figure this out!

I wish it were that easy! It takes 43.23 gallons of 2% sap to make 1 gallon of 66% syrup.
