1/2" Spears True Union Swing Check Valve - Slip X Slip

Spears makes the highest quality True Union 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. These check valves feature true union fittings on each end for easy replacement and disassembly.

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 than a project delay.
