I must agree Dean's comments, and I don't sell or service reclaim systems.
Even if you manage to find parts and service/repair this unit, you will have, at best, an inefficient recycling system rather than a true reclaim system.
The old Continental design with strainer basket, crude hydro-cyclone and activated carbon bed vessel has gone to bed with the dinosaurs.
Of course, if you enjoy occassional problems associated with pit odor, foaming, cleaning with grey water, low water pressure and premature wear and tear on spray nozzles, rotating unions, pumps, etc., it may be worth saving.
