RODI Issues

Be careful when buying a booster pump. The Aquatec 8800 is the standard of the industry and runs $122 including the power supply and pressure switch at PurelyH2o, a little more at Buckeye Field Supply and more still at Filter Guys. I am not a fan but Air Water & Ice and others have an off brand pump but its about the same price as the Aquatec 8800.

I use a 8800 myself and boost my pressure from 68 psi to a little over 90 to improve my GPD and water quality. I get over 110 GPD out of a 75 GPD membrane and at well over 99% rejection.

 

i received this from the PureWaterClub.

 

Pretty much what I pointed out. You need higher pressure
I would not run it at that low waste though unless they will guarantee the membrane in writing. It will fail guaranteed, I have seen this tried hundreds of times over the years and it does not work. If it did every RO vendor on the planet would have systems like that. Think about it, why would someone like Spectrapure who has been in business in the same place for 25 years sell their UHE for $900 retail if they could sell a simple system like that for $150? You notice Air Water & Ice doesn't have one either and they have been around for over 25 years, same with PurelyH2o who has been around for years and years. It doesn't work, well not for very long anyway. Probably just long enough to pass a 30 day warranty if that. This is not directed at any obe vendor but RO/DI vendors in general who think they can make a quick buck and get out of Dodge.

 

Interesting...

Housings, filters and membranes built in the USA and UPC, ANSI or NSF approved carry a 125 psi working pressure on them. Imported housings used on many off brand or ebay type systems generally are not approved or listed so they are protecting their hides. Buy a name brand RO/DI and insist on housings by Amatek or similar and John Guest speed fittings and you will not have any troubles. My Spectrapure system has run at 100 psi for months with not a single drip. Quality costs money.
