Pressure switch works okay, but I've found its not perfect because many times if you spring a leak, the pressure doesn't actually drop enough to shut the system down. If it's a shut off when your...

Sick the Vermont Attorney General on them. Back in 2011 they won a case against McDonalds for the Fruit and "Maple" Granola they were peddling....it was using extract. Needless to say, VT won and...

Hi rlapointe,

I had my start in hobby ROs last year with much the same issues to are seeing. It was immediately an issue for us because we have very high sugar content (this year's average has...

No issues to store it in the RO, I just drain my RO and store it where it is not heated. The membranes cannot freeze and should be kept cool, so those are stored inside where it doesn't freeze and is...

I do a soap wash with a concentration of water/H2O BioMembrane that matches the chemical cleaning pH level and temperature for my membranes. After flushing all existing sap/water out of the RO, throw...

Grasping at straws here -- how did you do your initial flush? Pure water or sap? I read somewhere else on the forum that it was advised to use only water as using sap could cause the membranes to...

How is the rubber seal around outer top of the membrane itself - you said something like they had wrapped them in plastic and shoved them in the housings? Is it maybe deformed a bit and letting sap...

Maybe, I was only able to identify the exact pinhole location the first time because it was misting under 150psi. It was right in the center of bottom of the housing where it comes off the form...

Crack wise, I was thinking more of a manufacturing defect. After patching the first housing I had that sprung a leak, I ordered a spare in case it didn't hold. When the next one blew a pinhole in the...

Looks good as far as I can see. You could try bypassing the 4 additional membranes and add them back into series one at a time to see if one of them is bad. If you narrow it down to one that starts...

deitzd-

Sounds like a plumbing issue or a bad membrane in the mix. I suppose it could be the o-rings and thats a pretty quick/easy fix if it is, but in the mean time, can you post a photo of your...

And I thought the 5.7 we saw today was good....that's just plain impressive!

Going back to my original comment, I would suggest you try putting all your membranes in series. You could also increase the PSI a bit. I run more like 150psi with 4x400GPD membranes in series and...

What do you typically see for sugar content? You may not have enough flow/pressure with the membranes in parallel to prevent them from fouling. I ran into that myself as we have fairly high sugar....

Looks like you are ordering them on Amazon? I've ordered from Albert's filter on Amazon without issue, but I recommend you check the listings/sellers to find "fulfilled by amazon" or "sold and ships...

We tested 3.7 last night, but that is not unusual for us as we're only tapping a few trees in an isolated bush with lots of sun exposure.

Great, thank you!

Fisheatingbagel - what did you use for a DE to syrup ratio? 0.5 cup/gallon? Honestly have no idea having never tried this, but interested... Thanks!

Better the wash bucket than the concentrate bucket while you're out of the room. +1 for spring clamps, though the clip Icefisher found is pretty slick.

We piled snow around our buckets when we put them out a couple weeks ago (tubing into buckets on the ground). Works pretty well as far as keeping them from blowing away, at least until the snow...

David - You don't necessarily need to clean, as in do a soap wash each run, but I would say you definitely want to do a flush and change your filters each time you run. When you are done running,...

No, I understand the preferred method, but I find even then, sometimes the cone filter doesn't get all the niter and you will eventually have a small amount settle out. I was just outlining how we do...

In our small operation, we filter multiple times throughout the boil...draw off, filter, continue boiling and then do a final filter just short of the right brix. Once we are at the right brix, we...

I don't really think its that funny. People pay good money for vintage and if someone is in the position to/wants to rebuild that evaporator to its original state, those castings are pretty...

Ah nice! I don't have any floats on my concentrate tank which is just a 30 gallon Xtreme cooler. I run a calculator and know my flow rates, so I know if my tank will be too full or not based on what...
