Pump Doesn't Pump....Just Hums

I found this forum today as I *sigh* seem to be having the same problem here in Chardon, OH. Although when I reached in with my 7/16 and turned it back and forth (was able to do so - without getting shocked :) it didn't seem to make a difference. Here are details: pump certainly seems to be running ok (starts up ok) but I have low flow. I am going directly to waste (bypassing the filter). I replaced all suction side pipes and it is air tight. In fact, when I turn off pump, I hear a swoosh of water that kicks back into the basket from the pump. When I open the basket lid the presuure relieves. So it seems like I have plenty of pressure but the water doesn't want to move for some reason (well, a little bit of water is moving but not much)...the pressure gauge isn't moving - just site at 5psi. I reached in and checked impeller which moves fine and doesn't appear to be clogged. It looks like I might have to tear the pump apart? Any other ideas on what's happening? Thanks very much for any insight.

I just went through a slightly similar problem with the low flow/no pressure problem. My housing was cracked on the pump basket and sucking in air. I wasn't able to see the water squirt out when shutting down due to the low pressure. Also the crack was at the very bottom.

RICK, welcome to the forum!!, you may have a clogged impeller or as Imnharris points out, a cracked pump housing. (there are a couple of other things, but they are much rarer). Check the lid of the housing for air bubbles - if you have air it will mean 1 thing, if not another.
Mayhaps this should be moved so as not to take over the origional post - Waste

thanks a ton. i did post a new topic (baffled-low flow) and I remain baffled...how can I check for a cracked housing?
