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
