swimming pool pump and filters

While the set-up should be balanced, as long as the pump doesn't exceed the filters pressure limit, you should be okay. Tom

My filters psi (maximum working pressure) is 50. Here is my problem. I asked for a 1 HP pump and the pool store gave me a 1.5HP pump. I hooked it all up and now my filter is not putting out much pressure back into the pool. I can literally cover the water coming into the pool with no effort with my hand. I have to backwash at least once a day and "bump and swish" about every 1/2 hour to get any pressure at all. I am thinking that maybe the pump caused some damage to my DE filter which in turn is causing my filter to not work efficiently. By the way, my water has been blue and cloudy since last week. I can see the bottom but not clearly. I am wasting everything out of the pool when I sweep and nothing is going into the filter other than water. I have tested my water and all areas are within normal limits, but my water is just not clearing up. Any suggestions would me appreciated.

Have you asked the pump supplier about this?

Questions: After you backwash, does the pressure increase?

Did you just start the pool up with the new pump -or- was the pump running, died, then you did a replacement?

If backwashing does not increase pressure, then there might be a blockage on the intake.

Does it have pressure before you add the DE?

Too much pump for that size pool. Gonna cost you $$$ extra to run it in the long run.
