spent about 4 hours looking high and low to no avail... I drained my sand filter when I closed it last season and I'm wondering do i need to manually add water to the sand filter before I start it up this season? I have a Hayward swim pro series sand filter with a multiport valve and I've seen people say just set it to filter and turn it on but that makes no sense due to pressure building and no relief valve. Others have said start it on backflow until water comes out then unplug then back to filter. Just need a definitive answer as to which method is the proper way.
Do i need to add water to the sand filter?

Welcome to the forum 
Do you have a psi gauge on your filter? Got a pic of your filter and pump?
That is the correct way. The pump will push the water into the filter and the air in the filter will be pushed out into your pool. I don't know why you don't have a vent (it's really not a relief valve) but, regardless, the pump will fill the filter and the air that was in the filter will be forced out into the pool. You'll get a LOT of bubbles at first.

There is pressure relief, the air & water flow back to the pool, you would only have a problem if the multiport was set to Closed (please don't ever turn the pump on with the multiport in closed position). You also can't change multiport settings with pump on.
Thank you so much for the response! Kinda feel dumb i didn't think about the air being pushed to the pool return lol. It's a slightly older system and was just worried the top would pop like a rocket lol.
Not a dumb question! I totally understood your concern, just reaffirming pressure isn't building in that "sense". There is a pressure gauge on the sand filter, but that is for a different purpose
Just when i get over my air pressure fear i see my patch i put on last season is leaking again....ughhhh can I put a patch on top of the existing one? Its right at part of the liner that rolls up the sidewall.
I have an underwater vinyl clear patch repair kit with glue was just wondering if the new patch going over top the old one would eat it away causing more issues
You would have to remove the old patch, you could try the gorilla on the outside only, my husband put it in both (outside & inside). The "real" pool patch & adhesive did not stick for us.
Due to the spot the tear is at I'm almost certain it would rip the liner further. Its at the very bottom where the liner starts to turn up the pool wall. I'm gonna try using my patch kit and place a larger one over the existing one and see if that works
You could apply the pool patch, then add extra adhesive around the edge. You could add clear gorilla tape around the outside of the pool patch just for extra leak protection. Especially if the tear is in an area that is going to flex often.
Got my skimmer fixed up. I swear we had to look like crazy people lmao had the wife inside the pool holding a styrofoam cooler lid over the skimmer opening so it wasent leaking while I sealed it lol. Had to get a Dang fan hooked up to dry the flex seal faster cause it would slowly bubble and then weep a little bit.... Now on the the underwater patch. Wife said if i give her any lip shes gonna hold me under longer hahaha y'all pray for me lol
That's actually brilliant!!
The support from the forums might be divided, just heads up... hahahaha!
