NF270-4040 membrane source?

[Bucket Head]

Since I now have 1.5% sugar in my permeate, and the unit was working correctly and then the permeate flow spiked, and my seals and o-rings are good/new, I can only assume I have some sort of internal failure going on with one or both of my membranes. Unfortunately, Joe at Atlantic RO is out of stock on them and will be for a while- Dow is behind schedule with them. Does anyone know of another, reasonably priced source for them?

Any and all leads will be appreciated.

Thanks,
Steve

the two I bought for my home made ro are H2Oinnovations H2O 70-4040 125gph around $280 a piece. but from what I understand they are very nice units so thats what I'm using

Try this guy. Good prices and service. No credit card needed. Ordered four membranes Monday by phone. UPS delivered today $20. I mailed out check on Tuesday. Prices are as good as JOE.

Here is another place to go. I have gotten membranes from them and they are the lowest price that I have found. They sell new or used.

I believe americanro.com is Joe's brother, so surely a good guy to deal with.
