Booster Pump Filter Cleaner v1

Custom Made Filter Cleaning Pump
These photos show the parts I used to make an easy to carry, easy to setup, and easy to use, high pressure filter cleaning system, based on a Polaris PB4 booster pump.
I wired a junction box to a Polaris PB4 pump so it could be connected to a outside electrical outlet, by a (custom) 100ft electrical extension cord. (I should have used some combination of a “pig‐tail w/GFCI instead, because it would have been safer.)
Next I used a custom ball valve connection on the inlet side which allowed me to connect a 25‐50 foot garden hose to the pump inlet, which allowed me to control the water to the pump (so I didn’t have to walk back and forth to the hose bib). Then I made a custom hose nozzle (which allowed me to control the water flow when I was cleaning the filter) and also permitted me to connect a shorter 15‐20 foot hose to the outlet side which I used to clean the filter cartridge(s).
Hose adapter fittings
This junction box has both a
receptacle and an off/on
switch (not shown) below it. I
couldn’t find (or easily make)
what I wanted; a GFCI, an
off/on switch, and pig-tail plug
so I settled for this because I
wanted the off/on switch to
cut the pump while still letting
the water go through.
I then modified a 100ft
extension cord so it had a
plug on each end. This is
NOT – NOT – NOT
recommended, because if
you plug the cord into an
power outlet first, you can
get a nasty shock if the
end that plugs into the
pump is disconnected
accidently or comes loose.
Inlet hose connection – allows you regulate the water to the pump w/o having to go back and forth to the hose bib. Especially useful if the hose bib is more than a few feet from the pump.
Hi pressure nozzle – allows you regulate the water to the filter w/o having to go back and forth to the pump. Especially useful as you switch from one cartridge to another.
Shows how the inlet and outlet hose connections should be attached to the pump, before you connect the garden hose.
