  • 1/4" in line check valve By Dave on 5/8/13

    After 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 3/6/13

    Use 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 3/5/13

    I 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.

  • Great Product By dgil71 on 7/10/12

    Super great price, works like a charm. Purchased two of these for the RO. One near the autoshut off and the second near the waste water hose to preven backup from the sink's drain.
