- Mur-lok Inline Check Valve 1/4" x 1/4" Push Connect
Get several for RO units. By Turf on 10/15/13Turf would recommend this product to a friendIn my experience I don't use my RO-DI more then once ever two weeks to fill a 30 gal top off tank... because of this, the outputs and inputs not being sealed, and how the RO membrane is oriented (on top and sideways) mine tend to dry out and reduce capacity much faster then it should.
I put one of these check valves on the end of every line in and out which has help extend the life of membrane from being as little as a month of consistent output at times to considerably more.
Thank you to BRS for helping me trouble shoot my system.
1/4" in line check valve By Dave on 5/8/13Dave would recommend this product to a friendAfter watching one of many Bulk Reef Supply videos I purchased an inline check valve to prevent water from back flowing through my DI resin. Since I've installed the new valve I've noticed that my resin last longer.Having many different RO dispensers (faucets, ice makers) BRS was very helpful in answering questions regarding its installation.
Thanks again BRS you guys make reneging simple and affordable!
Don't worry, check valve By BRDrDRD on 3/6/13BRDrDRD would recommend this product to a friendUse multiple check valves to keep everything flowing in the right direction. BRS is the cheapest price you will find.
RODI only - Not for saltwater use By Taylor on 3/5/13Taylor would recommend this product to a friendI was using 2 of these check valves with a Y - adapter to connect my water filter waste and an auto water change pump (located in sump) to my sink drain.
The check valve connecting my auto water change pump (Tunze) failed after 3 months allowing water filter waste to drain back into my sump.
The water filter waste check valve (non-saltwater) is still working fine and appears to be a good design.
When I contacted BRS for support, they informed me that the check valves are not intended to be used for saltwater; they should only be used in non-salt applications such as RODI water filters
I am purchasing a second drain saddle clamp for my sink to resolve my issue (and carbon to clean my water). Luckily I noticed my issue within about 10 days.

Adding some upgrades to my 4-stage Plus RO/DI. I want to split my product line to two separate locations. If I do the split after the check valve (included in the *Plus system) would I need to add any more of these? Maybe one for redundancy?
Bulk Reef Supply Hey Randy,
Sorry but the image doesn't seem to want to cooperate. That said though, no extra check valves should be necessary as long as its split after the check valve . The included check valve on our units is in the membrane housing so you couldn't split before it if you tried. As far as running to multiple locations, its as simple as a tee. I would recommend adding an inline ball valve to each side of the tee so that you can manually control which one is filling if you desire (otherwise it will just favor the path of least resistance). Another option would be to use a 3 way valve, though personally I prefer the two single inline valves as not only is it a bit cheaper last time I checked but you also have the option to leave both open, so in theory it would fill the first container, when the float goes up be forced to go the second container, and when that float goes up be done. With the 3 way ball valve you would have to manually switch from one container to the next. Just my two cents worth :-)
We believe GA Murdock Mur-lok fittings to be the best so strongly that we use them virtually exclusively on each of our BulkReefSupply.com reverse osmosis units and BRS media reactors.
