I recently took delivery of a Sears model 752050 gas powered pressure
For winter storage the manual has several recommendations including
usage of a "pump saver" additive.
Curious what real world users recommend for storage over the winter and
other extended periods.
I've had mine a 2750 PSI DeVibliss for 4 years and have done nothing but
use a fuel stabilizer and drain the pump. This spring it wouldn't pump
right away until I grabbed and released the trigger a few times rapidly
but other than that no problems. I think this year I'll pour some RV
antifreeze in the pump after it's drained.
Engine: Run the gas out of it or mix Stabil into a full gas tank.
Pump: Manually fill the pump with RV antifreeze............
To manually fill just rig a funnel to the pump inlet
and with the ignition off crank the engine until the
antifreeze runs out of the pump. Do not use standard
antifreeze. Use RV antifreeze.
Or purchase a aerosol can of pump antifreeze
for the same purpose.
Mine froze up one year. Cracked the pump inlet, damaged the trigger wand.
Luckily, I found repair parts and got it fixed.
Now, after the first frost, I remove the pump, hose and wand and store it
indoors. On my model it is a simple chore - three bolts and the pump falls
off with the hose and wand still attached.
