Sumo Max Flow pump is fast but…
This is my 2nd pump in 4 years. The first one had great flow volume and filled my 850 Sumo in a short amount of time. The only down side was the flimsy hose that comes with the pump. My hose tore repeatedly when new and and I kept cutting and re-clamping the hose back on to the pump to extend it use. I am very careful with my equipment, the hose was just lame. I ended up replacing the original hose with a piece of flexible PVC hose until the pump died. It’s a sealed unit so I had no way of diagnosing the cause of failure. I thought it should of lasted longer for the money and limited use. My replacement pump is the exact same pump and hose construction. I partly zip tied the electrical cable to the hose to try and strain relieve the hose with the cable. I guess I will see how long this one lasts.
