finally taking the step!!!

i am finally having sprinklers installed at my home. no more 5:00 wake ups to setup the agricultural sprinklers in the front yard. i am having a company come in and install the pipe and heads to my boxes, from there i am doing the rest. he is running 1 main and i am going to use 1 inch manifold with a 1 inch BVP. my question is, i have a 3/4 water supply that i am going to upsize to 1 inch to feed the BVP. Where should i change over to 1 inch? should i do it dorectly off the T from the main or should i run across the basement in 3/4 and change over to 1 right before the BVP. the total distance of the run will be a little under 30 feet. cant wait to hear back from you guys!!!

Connect the 1" as close to the water meter as possible. Assuming the sprinkler pro said that 1" was needed.

Pros who cut in a connection to 3/4-inch copper near the meter use a tee with a one-inch outlet to the sprinkler system. Don't cheap out here, and yes, we know what one-inch type-L copper costs.

take your time and buy the copper at a real plumbing supply, if you want a minimum of fuss - the key item will be the 3/4 x 3/4 x 1 "bullhead" copper tee, which the home centers may not carry

If you do want to cheap out on material, I would recommend using CPVC plastic pipe and fittings, as it will definitely be strong enough, and it doesn't present the "instant inspection failure" that the ordinary white PVC pipe and fittings will, when used indoors.

i am definetly going to be using copper. Would it be beneficial to me to put a 3 piece union directly below my BVP for servicing if i have to

You need a way to blow out your lines in the Fall. A tee with a threaded end in which you insert a threaded plug - or something compatable. Not sure where you would put it, wait for the pros to respond. Wait a second - are you talking about a PVB? - pressure vacuum breaker? If so, they go outside and below it you can install the tee I was referring to. Might be a better way to do it, but that's what I did. Also, consider a PVB with built in unions so you can take it inside in the winter.

Wetboots? How about pex with bite fittings for the inside work? Pex is cheaper than copper and easy to install, but the bites are expensive.

Nothing is wrong with PEX, but it can't handle the water pressure that sch 40 CPVC can, so it isn't as good of a sight-unseen recommendation. Also, you need special tools to assemble PEX. CPVC goes together with the same kind of cements we use outdoors on ordinary PVC.

The distinction of using CPVC for indoor work, as opposed to the less expensive PVC, comes from codes that no longer allow the indoor use of PVC for potable cold-water use.

I've used pex only with the gatorbites since I don't want to do crimping.
