Title: flowjet pump screeching sound when pressurising
Post by: STEVE-UK on May 08, 2015, 07:05:01 am

We have used Shurflo pumps for years with no issues, We were kitting a new van out and decided to try a flojet pump as they seem to be recommended, We bought the pump from Gardiners

Since day one the pump makes a screeching when pressurising, To reduce this we lowered the 'Cal' to around 20, This causes the rinse to pulse when cleaning high level windows

Is this noise a fault or just a characteristic of Flojet pumps?

Mine does it too. I think there's a pressure relief valve inside somewhere, I had to back the pressure down to stop it. Not impressed with it for what they cost.

I  had to loosen  pressure switch screw to stop it with mine after having chat with Oliver from GrippaTank.
