Asked on 04/23/2015 by John Mac

Could you be so kind as to suggest whether a HAYWARD S310 TOP MOUNT FILTER would be suitable for a :- 13000-15000 galls water 2" plumbing & would it maintain enough pressure for the pop-up cleaners Thanks

Hello John - The S310T2 would be suitable for your pool. The pop-up heads are dependent upon the HP of the pump. The S310T2 will have no effect on the pop-up heads.

We have this filter. We are considering switching from chlorine to salt water pool. Will this shorten the life of the pool filter? How many years of service can we expect out of this filter? Thank you.

Good afternoon Roy. A salt system will still be a chlorine pool, it just makes it now instead of you adding it to the water. The tank will be fine and not affected any more by the addition of the salt system. The balance of all chemicals is what extends or shortens the life of your equipment.  The tank should last 5-10 years, depending on the environment. The hotter or colder the weather, the harder it is on the tank material.
