We just moved into our house a month ago. It took me 3 weeks to get the swamp swimable which was great for a week. Now we just vacuumed and backwashed and can't get the multiport to engage in filter mode. Water keeps coming out of the backwash line no matter what we do. This happened every other time we vacuumed as well but we were able to get it to stop after turning the multiport a couple times. Since I found this site after week one I have avoided the pool store but is this a time it's ok to go talk to them? My husband is a big DIY guy so after a couple you tube videos he is ready to replace it himself but I am wondering if I should let him or not.
