I had to replace our whole house plumbing recently. We had very acidic water and it was slowly destroying the copper pipes. We have well water that is treated with a neutralizer. But the amount of continued corrosion had to be stopped. Initially I had to open a wall and ceiling where the main waste line (PVC) had a few leaks. So, I figured there was no better time than now to replace it all. I have installed a Viega manifold with all home runs to every outlet.
I used 1/2" color coded Pex with the crimp copper sleeves. I could not run 3/4" because of limited space, but thought about it. I ran all of the pex up two separate chases. One for hot, one for cold. No kinks, and all penetrations fitted with pex supports so no chance of abrasion.
Supplying the manifold is 3/4" PVC on cold side and 3/4"Copper on hot side. I have a sediment filter inline on the cold side just after the neutralizer filter. which in turn are fed by 2 bladder tanks that are just about 4 years old. The reason for two is the fact that the crawlspace where they are located is just about 2' tall.
Now my question... We had no significant pressure loss with all copper, but now we do when running more than one outlet. How do I increase the pressure on the whole system? Do I increase pressure on the bladder tanks? Do I turn the screw on the pressure regulator? That one seems the most obvious.. But before I do, I just wanted a bit of clarity.
Thanks - Tom
