My cat pump 290 started dying on me and instead of repairing it I decided to replace it with a cat pump 3cp1120.3.
I have the new pump installed, but while cleaning carpet the pressure drops about 200psi when I'm on the trigger. When I have it set to 1000psi for tile it drops to around 600psi when I'm on the trigger. Also if I hold the trigger while cleaning the tile, after about 30 seconds, it drops to about 200 psi and I have to wait a little while for it go build it back up.
The last thing I noticed is when I let go of the trigger I hear a whistle noise, which sounds like it could be coming around the pressure gauge.
I tried to look for leaks with soapy water, but couldn't find any.
