Do you use the spray bar??? Whenever I shut down the filter, I insert the spraybar inside a knee-hi. I twist the end so it won't pop off. Once the filter is restarted and the "blowout" is over, I remove the knee-hi.
Great ideas everyone! I've also used a pump to push a cottonball thru the hoses to clean'm as advised by some, but it does take a bit of ingenuity to get it the right size to do the job, patience, lol....Dottie
