We just replaced our Hayward S210T 200# sand filter with a larger Hayward S244T 300# sand filter. The old filter cracked and we were told it was under-sized for our pool and that a larger filter would clear the pool more quickly when it got cloudy, etc. We just got the new filter all setup and I'm curious if a couple of things are normal or not.
1. The new filter is running at 16 psi clean. Our old smaller filter ran at 10-12 psi clean, and I thought a larger filter would run at a similar pressure or even less? We did move the filter location. It used to sit up about 18" above water level and the new location is about 3" below water level. We have 1 1/2" pipe.
2. We just opened our pool and it was full of algae. I started a SLAM and started using the filter and I was having to backwash every two hours on average. The pressure was rising to 20+ psi really quickly. Our pressure never rose that fast on the old filter, even when clearing algae, and again since this is a larger filter I thought there would be more time between backwashing.
3. Last thing, I backwashed and rinsed the sand thoroughly before starting to filter. It has backwashed out at least 3+ cups of sand so far and there is a decent amount of sand that gets in the sightglass after each backwash. Is this normal for a new setup? The sand was AquaQuartz purchased at Leslie Pool Supply.
Thanks!
