    Is this check valve threaded at bothe ends?

    Thanks
    Question by: Mike on Feb 26, 2014 11:58:00 AM
    Hi Mike,
    This fitting is a slip fitting, it has no threads.

    are these threaded or slip?
    Question by: Ian on Feb 12, 2014 5:06:00 PM
    Hi Ian,
    All of the fittings are slip (as this is "normal") unless specifically labeled as thread. In the case of these valves they are all slip.

    Can this be used with vinyl tubing and a clamp? Or just PVC?
    Question by: James on Jun 15, 2014 6:07:00 PM
    Hi James,
    This fitting only has slip fittings (for PVC pipe) but you could glue on a set of barb fittings if you wanted to use it with vinyl tubing and a clamp.

    Are these listed as the internal or outside dimentions?
    Question by: Mike saak on May 15, 2014 3:49:00 AM
    Hi Mike,
    PVC fittings are sized in a "nominal" sizing. Neither dimension will read exactly the same but the nominal size means that a 1" check valve is going to fit a 1" pvc pipe, which will fit a 1" elbow, etc. The standard is the same across all the PVC as well so a 1" sch80 check valve will fit a 1" sch40 pipe and so on.

    The golden rule of plumbing is that every job takes three trips to the store. While this can be frustrating locally it can be much much worse when shopping online. Being short a fitting or two can delay a plumbing project for days. Here are some quick tips to avoid this.

    • Plan your plumbing on paper
    • Don't skimp on unions. Unions allow for easy breakdown and maintenance as well as remove the need for precise elbow placement. Use them as often as possible.
    • When in doubt order extra. We happily accept returns for a full refund (less shipping) on all unused fittings within one month of purchase. A few extra bucks in return shipping is less frustrating then a project delay.

    • Works Great By cocochevelle on 2/3/2015

      I got tired of the submersible pump in my sump and decided to put a Reeflo Snapper on my 55 gallon. I used the Spears 2" check valve on the output side of the new pump and then above the Spears, there' s a 2 inch ball valve (Lowe's) to adjust the flow. Works great so far!

      I recently ordered the 3/4 inch Spears Schedule 80 Check Valve.

      You will additionally need when choosing to use flexible hose as a return from the Sump

      Bulk Reef Supply:

      2 count Sku # 202544 3/4 Schedule 80 female Pipe Adapter

      2 count Sku # 202656 3/4 Schedule 80 Straight Barb X Male Thread

      *** AND! a trip to Lowe's for: ***

      Two 1 inch sawed pieces of 3/4 inch X 5-FT Sched 40 PVC Pipe

      Two metal hose clamps

      and Water safe hot and cold GLUE

      Sand off the sawed PVC parts ( I could not find 3/4 inch coupler so thats what I had to do.

      Make sure you install on a 90 degree angle and there you go

      Hope I saved you atleast one trip or order from my experience
