We installed. I'll get model number an name of manufacturer the backwash value you have to push down turn to slot and release and yes I will post a picture of the plumbing that me and my husband done not the greatest I guess we're trying the directions that came with the pump might as well be in another language other than English. Oh wait it does. Lol. because I don't understands it. Info on dials are nothing, basically nothing about pressure anything so we've been working on info from google we put a hundred and fifty pounds of sand in
Yes it was in the backwash position. An when u say what filter size is,that the container with the laterals in it other than that I don't know where any other filter would be. We purchased sand for it at a pool store they were 50lb a bags. An sand came out after we loaded it an filled it with water the first time an tried to backwash sand as the pool store told us to do before use on pool.
It is possible that you've over filled it with too much sand. If it's a model SD35 than it only needs 100lbs not 150. Anytime a sand filter has too much sand it will naturally expel the excess during backwash until it gets to around the correct filled level. When back washing all the sand is lifted and as this happens the dirt is displaced and lifted through the grid on the underside of the multiport. If theres too much sand the water pressure during back washing will force all that extra sand up higher and out to waste.
If it happens to be a SD40 then it does require 150lbs of sand and there is something seriously wrong with the multiport.
IT'S A SD40 150 LBS OF SAND IS THE REQUIRED AMOUNT. THANK YOU FOR THE QUESTIONS. WE'RE JUST GOING TO START AS IF IT WAS NEW AN SEE IF THERE WAS A MISTAKE WITH ASSEMBLY, SENCE IT WAS USES WHEN WE GOT IT.
Okay thanks. Not sure why they would sell this an a unit , I'll have to talk to manufacturer see why that they're misleading their customers by selling improper products together thank you guys for your help have a good day
