We have a 1.5 hp that runs a "weeping wall" type waterfall and two bubblers on the tanning ledge. The pool builder insisted that we needed this much power to run the features. He apparently likes the sound of Niagara Falls and 6 foot high gushers on his tanning ledge. We, however, prefer to have more of a gentle babbling brook effect.
There are two valves that control the amount of water that goes to the two features. I have to shut these down almost all the way to get the amount of flow we desire. My concern is that I am causing too much back pressure on the pump. Is this really a problem or am I worrying for no reason? If I am flirting with disaster, is there anything I can do other than replace the pump with a less powerful one?
