Rated 4 out of 5 by from Tight seal critical After having difficulty with this machine, I decided to seal all suction connections with marine glue. Once all sealed the machine performed as advertised. Tight connections are very critical as any slight leak of air will cause machine to not suck any water.

Rated 5 out of 5 by from Great pump I bought the CW20 to pump water from a river to irrigate my lawn and it works great. It pumps a lot of water and am very satisfied with its performance, Very simple to use and I highly recommend it. No problem pumping water through 300 feet of hose at slight incline.

Rated 3 out of 5 by from Has great features but bad quality end piece that you hook your hose to. Needs to be made out of steel not pot metal. Breaks easily!! We have had 3 Generac CW 20's in the past 8 years. All have broken off in the same spot where you connect a hose. Piece you connect to is cheap metal not hard steel. Recently we got a new Generac & second day we connected a hose to pump end it broke off. We called Generac & they did send us a new piece free since it was still under warranty. Pump works great but Generac company needs to put a better quality part where you connect a hose.

Rated 4 out of 5 by from PRODUCT DOES WELL Product worked well first year of using it Second year and this year primer cap will sometimes blow right off machine or partially . Replaced cap and seal this year and started doing it again. Disappointed with this only run maybe 10 to 15 times a year. Also top cross bar weld broke first of having it. Great product when it works

Rated 3 out of 5 by from Almost good. This product is almost a success with one GLARING failure. Everything seems of high quality and the pump has functioned flawlessly. However, the big flaw in an otherwise great pump is a absolute garbage pull handle. Who approved this!? It has huge sharp flashing all around the inside edges and immediately sliced two fingers on the first pulls and then half broke off in my hand. How could anyone have thought this would be acceptable? I immediately went and bought a high quality replacement handle and it made a good pump out of it. A $0.20 part makes an otherwise great product seem very poor. Generac! Pay attention! Charge the extra dollar and install a good rubberized pull handle. There is no excuse for this one made of reclaimed toilet paper and razor blades.
