RO / Backflow preventer


So we are selling a home next week and the buyers inspector is requesting us to "Install a backflow prevention valve in the RO system". I cant find any info online about where said product can be purchased or if I find it, where within the network of tubing I would install the thing??

Any ideas?

Ask if a spring check valve between the ro and the main house line would work?
There are plastic spring check valves that can be had that are 3/8 or 1/4 in and out.

Also ask as to Why there should be one as every ro system that I have seen does not have one, and that is from the cheep box store to the more costly ones.

RO / Backflow preventer


The company I work for does quite a bit of commercial plumbing and when we are required to hook up an appliance like a R.O. System or a hard piped coffee brewer we are required to put in a back flow preventer between the branch line feeding the appliance and the appliance itself. We typically use like a Watts Model #909 or #919. Some of the back flow preventers (mainly a RPZ type) will require an air gap and route to a drain. So keep that in mind before making your purchase. I do not know if the big box stores carry these, but I'm sure your local plumbing supply house will.

It does have a line going to the main drain of the sink. So just put a check valve in the feed line and call it a day?

Yeah I would see if they think a check valve would be enough. A backflow preventer is a little more complicated of a device; it has a couple of isolation valves, a couple of check valves and some test ports. In your situation I would think that a spring check valve would be good enough.

Disconnect it and sell the house......

I've been looking through my UPC book- if RO is considered a pure water treatment system and you're governed by the UPC then it needs protection like dannyoung suggested. That's my interpretation

Install an ASSE 1022 backflow on the RO drain line. That will make you happy...
