Hello,
I have IM Nuvo 40g that I replaced the pump a couple of years ago. The new pump was slightly bigger then the stock pump and when I put it in it was too big so it had to be tilted/lowered in and then I could screw on the return hose. The pump would not go in with the return hose attached and facing in the right direction. So, I put the pump in, screwed on the return tube with my hand/arm down in the chamber. When it came time to service the pump I could not unscrew the return tube from the pump (at the base of the pump in the chamber with my hand down it) to get the tube off. The tube has to come off before the pump can come out. The chamber is about 20inches deep. At first I thought it was just stuck or I wasn't strong enough so I had a guy (big guy) friend come over and he couldn't unscrew it either. Fast forward to a year later and the pump really needs to be cleaned and almost has no flow at all. Not surprising at all. My question is - Does anyone have any ideas that I'm not thinking of? My first thought was get someone stronger to help, that didn't work. My second thought is to cut the intake tub off and replace it. But does any one have any ideas on how to go about that safety and/or tool suggestion? The space is so limited and the chamber is all glass. I couldn't get my hand plus a wrench or something down there. The tank is not empty, it is up and running - just poorly.
Thanks,
Dell
