SWG wont run on low speed

[nfusion770]

I just installed my first pool. When I fired up the Jandy Aquapure ei I got a no flow message. I flipped my 1 hp pump from low to high and immediately the generator started to work. I am guessing the flow rate at the SWG is too low to run on low speed. Do I have any options other than running the pump on high all the time? Could this be a plumbing issue as there is a 90 about 10 inches before the SWG but I am pretty sure this meets manufacturer recommendations. Any ideas? Thank you

there is a chance that with a longer run in front of the SWG/flow sensor it would turn on with the low speed , but no guarantee unfortunately.

Thanks. Tough to justify re- plumbing without knowing for sure.

It's not recommended, but you may be able to by-pass the flow switch, or maybe see if they offer one with a lower flow rate.

Maybe I will call Jandy and see what they say.

Thanks.

Has your sand filter been backwashed recently? My flow is too low for my swg when my filter pressure goes up about 15%(measured on high speed) when running on low.

Yes it has. I just started the pool last week and backwashed a few times to get the rust out of the filter. Now I plan to let it run normally. It might have to do with the plumbing. I didnt plan to have to leave 12 inches between elbows or to have 30 inches between the sensor and the cell so we had to plumb it a bit weird to meet the specs. I might have to call Jandy to see if they have any ideas.
