Rainsoft 2000 brass valve rebuild

Unit was down for some time and I finally got around to working on it. It probably has sat for 3 or so years. Original problem turned out to be timer motor. Gear was stripped so motor was running but timer was not turning. Replaced gear and now unit cycles. Problem now is probably worn seals from sitting for so long. Looking for info on this. I get no brine draw and when end of cycle there seems to be a slow water leak to drain. Both tabs on brine draw and fill seem to be present so they are not broken. Best guess is seals.

Thanks in advance
