Superior Pump 99522 Reviews & Ratings

Is This Really A 1 1/2 Inch Check Valve? No
By Larry Urbanski
Orland Park, Illinois
Purchased 11/23/2015 |
Review Posted 12/15/2015
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 1 1/4 check valve fit with 1 1/2 inch hoses.

Expert Response
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
By richard
ridgefield, Connecticut
Purchased 03/07/2011 |
Review Posted 03/10/2011
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 into an outside cistern and there was so much momentum reaction at the outlet that the pipe rose 6" when the pump was running I had to put a concrete slab on it to hold it down!
I can tell that I won't have any problems with this pump keeping up in a torrential rain.
I also like the design of the fully adjustable external float switch.
Great product and very timely delivery. Thanks!
