Thanks geeman. Do you do a neutral pH startup with the SS when you don't add the 3M?

About to have new pool plastered, and looking for any experiences with an additive called Silicone Shield. Plaster will be white, and I am trying to find the best durability/stain resistance achievable. Thanks, Bcatv

Thanks PC, I'm a little concerned; there are several valves, pumps and filters involved, so could have some shaft leakage. I also should have made clear that this is air-only, there is no water in the plumbing as yet. Given the mass of pipe involved, would hate to have to find a small leak, but better now while the trenches are still open... thanks, Vince

Building a new pool with lots of plumbing due to size and in-floor cleaner, and wondering what typical pressure leakdown during test is. Plumber pressurized to 20psi Thursday afternoon, 48 hours later one pump/cleaner set is down to 10psi, the other is at 16psi. 3 Pentair valves on the lower set, 2 on the higher, 2 Paramount cleaner valves on the higher psi side, 1 on the lower, an Intelliflo pump and a C&C+420 on each set. Does this seem like normal levels of leakdown? thanks, Vince
