  1. My mistake was thinking it was broken!!! 5 Star Review

    Posted by on 24th Mar 2014

    Bought a new one. Thought my seven year old one making funny noise and no water was broken. Ordered new. Turned out our pipes were frozen and we had no water to the pump! Steamy Clean opened out line 150 Ft away and the old pump went back to working. Am going to hang onto new pump just in case but can't say enough for this pump! Nine kids. Two floors. Five bathrooms. All have water!
