no diff. after by-passing water softener. Raised pressure to 50/70 and there is somewhat of a difference. I have identified another problem that it very well could be, although it should not affect the cold side of things. The problem is that the supply lines to and from the water heater are only 1/2" copper. SO to recap my current plumbing line setup. 3/4 from pump to CVS to Manifold. I tapped into a 3/4" copper cold line coming from the manifold (back feeding) to temporarily keep house running, but it reduces to 1/2 going to the water heater, about 12' then it returns 1/2" hot, around 40' before up sizing back to 3/4 to feed the manifold.
I can see a very noticeable pressure difference in the shower when messing with the hot side of the vanity faucet. So I think maybe my pressure loss is allot more on the hot side. I won't be able to find out for sure until the hot water heaters are relocated and I can up size the supply's to 3/4.

No filters between tank and manifold, only the Water Softener, Ball valves are fully open and I removed the low flow limiter from the shower head. That being said, the distance from the tank to the manifold is approx 8' and distance from from manifold to shower fixture is approx. 20'. So 8' of 3/4 and 20' of 1/2 PEX, that doesn't seem like too much pipe, but I agree I do have pressure at the tank, but before the softener. All of this plumbing is brand new, even the softener. Do you think the WS could be reducing the pressure/volume? I say volume because I think its a volume problem more than a pressure problem.

Hello,
I have a question on Line Size.

I just installed a new pside kick system on my plumbing system and found out that I had a bad check valve on my submersible pump. I replaced the pump with a new 3/4hp pump (8.8gpm) hung on 1" line to pitless adapter. from there it reduces to 3/4: copper and runs about 14' to inside the house. This is where I installed the pside kick kit. I reduced fittings to 3/4" and ran the 3/4" output to a PEX manifold. From there it reduces again to 1/2" circuits. ALL of this is brand new. I just installed a new bathroom (all fixtures are new) and I'm not getting very much volume out of the vanity faucet or shower/tub (Delta fixtures). I am getting 50lbs of pressure @ 3gpm. In fact I can get 55lbs @ almost 5gpm, but when just running say the vanity faucet something like 1gpm it running almost 60lbs just below cutoff, but it doesn't seem like I'm getting that much pressure or volume. A garden hose hooked directly up to the low point drain will lift itself up under pressure, so I know i'm getting good output pressure 18" from the CVS valve but beyond that I'm flustered.
So do you think my line size is actually reducing my volume that much?
