RO/DI pressure

[texfromkansas]

I installed the Spectrapure 90 gpd last night. The pressure is staying around 58psi. Is that ok? Does pressure effect the way the system works?
THe instructions say the DI filter iwll change from a very dark bule to a light blue or tan color when it needs changed, mine is starting to turn orange at the bottom. Is that ok?

60 PSI is ideal. As the pressure gets lower, the filter still works, but the volume produced goes down.

The DI cartridge will start to turn orange/rust color at the bottom and work it's way up. It's supposed to be used up when it's totally orange but I trust a TDI meter more.
