I just picked up a used Homelite 150gpm trashpump. It pumps pretty well but doesn't put out the pressure that my brothers cheapo Chinese 145 gpm Harbor Freight pump puts out.
So far I haven't been able to find out anything about this pump. The only number on this pump besides the 150 gpm is 62989 which is embossed on the pump casing. Anyone know anything about these bad boys???

 

Can they be adjusted to increase pressure?
Possible impeller wear?

 

try searching the model number and/or pump description on ebay. You'll probably have any and all rebuild components pop right up for ya, maybe even a parts kit with schematic display in the ad.

 

go to this web site it is the company that now has the homelite it is called riverside pump mfg the web site is www.riversidepumpmfg.com/ it has phone numbers that you can call so maybe they can get you parts and a manual

 

That's the spot right there!!! They have a down-loadable owner's manual as well as a parts diagram. Seals or impeller wear are indicated as performance killers.
This is my pump.
Thanks man!

 

If it was ever used without a strainer debris and stones can clog vanes.
