Welcome to our forum.
J480 manual page 42... "Large debris are filtered when either jets pump is running when the spa is in use or during a programmed filter cycle.
Quick story! We had a couple of carney's get in a J-470 at the fair a year back, I opened the spa and the water looked fine, but their was a lot of sand/dirt in the btm of the spa and a beer can. We ran pump 2 which flows through the bag filter and with in an hour it was 90% gone and all deposited in the polishing bag which will hold close to 8 lbs of sand/grit, it didn't suck the beer can through though.
Any loose teeth in the bag?
sweet, great job termie. That sounds so good I almost believe it!
I daresay I have more credibility than ANYONE on this forum. Anybody can tune into my store 24/7 and see what goes on.What part do you find hard to believe?Terminator
So Jim, I am curious, is that polishing bag something that the spa owner would empty occasionally, or would it be emptied by a service person in the event of a problem?I know sometimes I get grit in the bottom of my spa and if I forget to take the turkey baster out to suck it up, it mysteriously disappears on it's own..so it must somehow make it's way to my filters.I have large ash trees around my house and if I leave the cover off my spa to shock, I occasionally get a few of those seed flyers in the tub..It has never been a problem as they quickly end up in the filters if I don't grab them out. What could happen if they, by virtue of a by-pass, zipped through my pump and heater? Just wondering in the worst possible case, what would/could happen?
