    I have a 2" sand point down about 35". Water level is at 26" I am using a Sta-rite 1 1/2 HP Horizontal multi-stage jet/centrifugal pump (Model HMSF). This is a single pipe system with 30' of 1 1/4" pipe into the 2" Casing.

    I installed the system about 4 years ago and I was getting a flow of about 12 gpm. Water level was at 26'. This year when I started up the system I am only getting about 5-6 gpm.

    So far this is what I have tried:

    1. I have pulled up the interior pipe and replaced the entire jet assembly/leathers. (Still only 5-6 gpm)
    2. I rebuilt the interior of the pump. Impellers/wear rings/gaskets were all replaced. (Still only 5-6 gpm)

    I am not sure as to what to do next?

    My sprinkler systems was setup using a 12 gpm flow and now it doing a very poor job.

    Help!

    I assume you mean the Leathers on the Single Pipe Jet. Right?

    That's a lot of Pump for that kind of water level and well size. That is one of Sta-Rite's most expensive Pumps and the two Impeller design is for deeper water levels. Like 60 foot plus. The extra Impeller in your situation is hindering water flow instead of helping it. Nonetheless, you have already discovered that you rebuilt the Jet and Pump for nothing. Now is time to look at the Well. That is your problem. Either the screen is plugging up, or the water level has dropped.

    So any advice on how to easily try cleaning the screen?

    Nobody said it would be easy.

    Is this Sand Point out the end of the two inch pipe or attached to the end of it?

    The sand point is an extension of the two inch pipe.

    Would turning the two inch and running a garden hose down it do the trick?

    So your saying it's a two inch point screwed to the bottom of the two inch pipe?

    No running a garden hose down the pipe won't help at all.
