How far can you run 1 inch water line?
Vertically it can lift it a little over 92 feet. The issue with horizontal distance is friction loss.

Is Zurn PEX-A or B?
Zurn Pex, Inc. chooses the Silane (PEX-b) method to manufacture its tubing. While high degrees of cross-linking can be achieved using this method, it is unnecessary because the density of the base resin for Zurn PEX is higher compared to PEX-a and PEX-c methods.

Crimp fittings require copper or stainless steel crimp rings and a PEX crimp or clamp tool. Some manufacturers use O-rings on their metal fittings (manufactured to ASTM 2434 standards) to make the seal with the tubing. Crimp fittings are compatible with all types of PEX tubing, except for PEX-AL-PEX.
Can you expand SharkBite PEX?
Slide your expansion ring over the PEX tubing until it overhangs the end of your tubing by no more than one–eighth inch, or until the stop on the ring, if present, touches the tubing. Using a manual or cordless expansion tool, insert the tool into the PEX pipe and expand the pipe.

40 PSI at the base of a building can push water up roughly 92′ but then keep in mind that the pressure will be FAR lower the higher up you get. The relationship between PSI and feet of head is that 2.31 feet of head(or vertical height) = 1 PSI.
What kind of pipe do you use for buried water lines?
HDPE (High Density Polyethylene) pipes are a considered the best choice for underground water lines. What makes this type of piping so great? HDPE pipes are non-toxic, tasteless, and considered a green building material. The pipes are designed to be high crack- and corrosion-resistant.
What is better copper or PEX?
PEX pipe is not only cheaper than copper but more durable too. PEX is immune to corrosion and mineral build-up, and it’s not affected by electrolysis, which can cause small pinhole leaks in copper piping. Copper pipes can last anywhere from six months to the life of a building.
Should I replace copper pipes with PEX?
While copper is an excellent material, no material is perfect. You can develop some problems with your copper pipes, and PEX is often a great replacement that can eliminate these problems.
