This past year I reconfigured my RO to increase brix output. I now have a 3-post 4x40 RO with a 10gpm HP pump running recirc. The pump output typically runs at about 225-250psi. I'm getting about...

Over the summer I decided to take the big leap and upgrade from the Procon 265 to the 660. I also added a supply pump because of the positive suction pressure needs of the 660. I kept the...

When I had this issue in my system sap would blow past the single o-ring right around 200psi and bypass directly to the permeate line. When you pull the cap off you might see the o-ring slipped out...

Assemble your vessel and take a look down the center hole of the end cap. Is the nipple on the end of the membrane fully contacting both internal o-rings? I bought a DuPont knockoff membrane a...

A few years ago I bought an older Memtek RO that originally had a 4x20 element with a 1.8gpm triplex plunger pump. The unit was upgraded to a 4x40 element at some point in its life. After I bought...

Thanks for the information. I've actually got a second 4x40 membrane that I was thinking of incorporating when I modify this RO. Do you think I'd be better off going with the Series 5 300 and put...

I've been doing some research on the Procon pumps and am thinking of getting the Procon Series 6 pump, which would give me up to 660gph. Our element is a DOW Filmtec XLE-4040. The spec sheet says...

We actually thought about switching to Mason jars as we can get quarts for just over $1 each. The problem with that is we'd have to come up with all the "required labeling" that is already printed...

I've got an older Memtek RO system that was previously converted from a 4x21" membrane to a 4x40" membrane. The original pump can supply 1.8gpm to the system, which is far less than the 4x40"...

Yes, I am talking about plastic jugs. I heard there was a shortage, but didn't think it would equate to a 30% increase in price. Supply and demand I guess. I just wonder if & how it will affect...

Is it just me or are syrup jug prices quite a bit higher this year? I bought a case of pt jugs for $120 last year and this year the same jug, from the same store is $175? Quarts were $144 and now...

Sounds like what I am experiencing. That is why I have a recir line installed in the system, which allows the pump to operate at peak efficiency. I modulate the recirc flow to get maximum vacuum,...

I don't want to hijack this thread, but I'm new to using the shurflo pumps this year. I've got two models; the 4008 (3gpm) and the 8000 series (1.8gpm). The best vacuum I can achieve is around...

Dr Tim,

Do you know what the micron size is of the pre-filters that go inside the cone filter? I'm currently using a 50 micron poly filter for pre-filtering and it works pretty well, but I've...

It was an expensive lesson to learn for sure!

Shaun,

These pans are 1980's vintage. Not sure what alloy of stainless was used back then, but sure sounds like using Chlorine to clean it was a big no-no.

Stored in my sugar shack (garage). Stays dry all year when not in use. Apparently I made the mistake of not removing all the carbon/soot at the end of the season. I brushed off the heavier soot,...

Not exactly sure what grade stainless, but it's not magnetic, so probably 300 series.

These pics are all from the bottom of the front pan.

The carbon on my pans is by no means "fluffy". I just spend about 5hrs scrubbing the pan to try and get the carbon deposits off. Easy-Off oven cleaner helped, but dtill took a LONG time. End...

Apparently these pans aren't made of high-grade stainless? I thought a stainless pan would be less susceptible to chemical attack than this? I get that I need to keep the equipment clean, but I...

Offroad diesel (ULSD). Nothing shiny on the pans. I've always struggled with carbon buildup, but my chimney has no smoke when operating. Figured it has to do with relatively cold metal due to sap...

I did clean the bottoms of the pans, but no to shiny stainless. I brushed the heavy carbon off and hosed the majority of the remaining carbon off.

I don't have any pictures of it yet. Stainless pans, welded. holes are in the bottom of the pans. For storage I did a citric acid soak and then did a chlorine rinse to kill off any "bugs" after...

I was out in my sugar shack last night, test firing my D&G 2x6 arch, looked in to the bottom of the finishing pan and could see several tiny pin holes all over the bottom of the pan and could see...
