Q: what does the check valve do for a sump pump and do I need one if Im buying a sump pump?
by Van from California on December 20, 2012

A: You definitely want to install a check valve along with your sump pump. The check valve will keep most of the water left in your discharge pipe from returning and emptying back into your sump basin once your pump shuts off, thereby preventing any rapid re-cycling or continuous cycling of your pump.

Is This Really A 1 1/2 Inch Check Valve? No
I purposely ordered this check valve on line because I didn't want a 1 1/4 inch check valve with hose adapters to 1 1/2 inch, which is what Home Depot and Lowes was selling. I wanted a full 1 1/2 inch inside diameter check valve like I removed from my sump pump. If you remove the 2 rubber hoses on this Superior check valve there is a check valve that is actually 1 1/4 inside diameter that also fits a 1 1/2 inch hose. Superior pump shouldn't be selling this as a 1 1/2 inch check valve. It is a... more

I'm sorry to hear of your displeasure with your purchase. While it's true that many of the check valves with rubber boot/clamp connections do not provide for full flow, the Superior model 99522 check valve opening is a full 1-1/2" whereas other check valves, including the 1-1/4" / 1-1/2" valves will be reduced down to 1-1/4". For a full flow throughout the entire valve, the Zoeller 30-0041 - 1-1/2" Clear Quiet PVC Check Valve would be the best option. If you would prefer to order the Zoeller 30-0041, I'll be happy to issue you a full refund for your Superior check valve.

Stormpro Sump Pump
Received my new pump last night and installed it this morning with a forecast of more torrential rain.
My old pump (not StormPro) had developed an intermittent electrical problem and I could no longer trust it to keep working during a storm. Pump failure would mean another big bill to fix a drowned heating plant!

I am a professional engineer and this little pump has almost twice the discharge as my old pump at the same horsepower. The ABS discharge pipe goes through a 90 degree fitting... more
