I'm buying a house that has a Fox 14x28 inground pool (vinyl liner) with buddy seat. It was built in 2000, converted to salt in 2015. At age 72, this will be my first pool ownership (I can't believe I'm taking this on now). I'm trying to get up to speed before I move in, so I've been reading this site. I'm sure I'll have more questions later, but this one will help me "get my feet wet" here [sorry]. Although water comes into the pool via the buddy seat jets, the "knobs" on top of the seat have no effect on anything. The current owner says they control water flow with the valves at the equipment pad. Please tell me where I can buy replacement seals or valves or jets or whatever I need to get the seat working properly, both for returning water to the pool and for massaging. The current owner says the walk-in steps are also jetted, but I haven't seen any water moving from them when I'm there (another town). In my signature, I've put the equipment I *think* will be there, as best as I can tell from the photos I took when there. Thanks very much.
