Question:

Small lawn irrigation system: can I run 3/4 inch PVC pipe from 1/2 pipe?

I have a garden faucet on a 1/2 pipe, from which I plan to run PVC pipe to 2 Rain Bird 3500 sprinklers at 20 and 60 feet away (and are down grade slightly from the garden faucet). I am think of 3 options for pipe size: (1) 3/4 pipe for everything, (2) 3/4 for the first 20 feet, then split to 1/2 pipe to each sprinkler, or (3) 1/2 pipe for everything. Assuming very good water pressure, would 1 or 2 work? Or would I probably lose pressure by going from 1/2 to 3/4? I'm thinking that the 3/4 pipe will compensate for friction loss and volume supplying 2 sprinklers.I do know I should get a water pressure gauge and design this with the charts, but I'm on a small budget and it's only 2 sprinklers. Thanks in advance.

Answer:

How about YOU stop advertising that you're maturity level is a lot smaller than your shoe size!
Will, are you the renter or the owner of the building or just inquiring? Some places in the USA are in their 10th year or so of drought so I'd think if it weren't a law to have a fire extinguisher than one should buy their own. These days it's a must have. And surely a must have if you don't have a sprinkler system in the store or apartment.
