I'm not familiar with them either. Can they be retrofitted into a Hamilton DRS? Does inexpensive translate into problematic or a good value? What's the maintenance protocol? Am I being overly cheap or is $150-$200 per unit for a tune-up every 12 - 18 mos. excessive?
Yes the Pyramid validator can be retro fitted into a DRS changer. The Pyramid validator does not like any water. I've got a few out that I sold 5 years ago that are still in service.
