Spears makes the highest quality check valves. Use them to add a last line of defense against overflows. Check valves allow one directional water flow and are used to prevent back siphoning. They are commonly used on return pump outputs to prevent water overflowing the sump in the event of a power outage, pump failure or maintenance.
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.

This fitting is a slip fitting, it has no threads.
I am planning to pick up the 1/2" version , the barb insert to use with this check valve is it this one ? 1?2" Pipe Adapter Spigot x Barb
The Spears swing check valves are not serviceable. You could always clean them with vinegar, but the actual seal cannot be removed from the valve, like the George Fischer Wye check valve can.
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.
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.
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.
