adding yard hydrants and sprinklers from the water meter

We have finally decided enough with the hoses, it's time to install some yard hydrants. I am planning on tapping off the water supply to the house and was actually considering doing it in the water meter box. My 2 main questions are, what type of piping do I have and what type/size should I use.
1. The piping that is in the meter pit and where it comes into the house is bright blue plastic and is about 1 1/2" or 2". Is this PEX or is that not enough info to know.
2. What is the most economical type of pipe to run underground? I was originally only considering 20' sticks of schd 40 PVC, but then I thought a continuous roll of PEX might be better.
3. What size should I use? I plan on running a main line that is approx 300' long. Off of that, I want 3 yard hydrants on legs that are approx 25' long. Next to one of those hydrants I am planning to leave a capped pipe so I can come back in later and add a sprinkler system for the back yard.
4. Anything else I should think about?

I would not do work inside the water meter box unless the water company specifically allows that. I would be prepared to dig a pit next to the water meter box.

I would use at least 1-1/2 inch pipe for lower flow resistance and more pressure at the far end to be able to drive more sprinkers simultaneously.


The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.
