It was a mutual investment in time. Katie and I were there for 6 hours. During that time, we pulled the filters, stripped the o-rings and reinstalled older 'but still good' o-rings to interface with the equipment (top o-ring only), clipped off the pintle caps, removed the spacers and lower rings, wire wheeled the rust/old paint, solvent tanked them, ran them through the ultrasonic cleaner, flow tested them at 80% and 100% duty cycle, then blew them out at 100% duty cycle with compressed air, manually filled them with injector preservative for storage/shipping.
Chris still has to 're-ring' them and install new pintle caps, but I bet that'* already done. His wife, who also works at hp was in FL on business, which really tied Chris up with the baby.
But it was worth it for several reasons:
1. Cleared out the FIE backlog. Chris doesn't like to get behind.
2. Got the pool flowed for other members here.
3. Re-flowed mine for peace of mind. They still look great after 2 years.
