how to install a sprinkler system by myself ? layout? tap into water line?

Answer 1

you can't do it. You can do all the work except hooking up the water. That has to be done by a lic plumber (some places even state Master plumber) you need to hook up a deal the will not let the water from the system drain back into the house water

Answer 2

The easiest way is to hook your underground sprinkler system to the garden spicket that comes out of the house. Just remove the faucet that is currently there and replace it with a splitter, one side will be the faucet and the other will attach to the sprinkler system valves. Each valve will control a segment of your sprinkler system. You will need to figure out the water pressure with a gauge of your supply before figuring out how many sprinkler heads you can put on each valve. Obviously, there are hundreds of different types of sprinkler heads, but I use rainbird. You'll need to design your system so that each head's water spray overlaps the head next to it, for full coverage. Half cirlces are good for the border to outline the lawn, while full circles and rectangles are good for the inner portions of the lawn. I use PVC pipe for mine, but I live in a warm climate. Once you get the layout done, you'll need to mark the areas of the lawn where you will lay pipe, and trench it about 3-4 inches deep.

You will need PVC pipe, pipe cutter, PVC pipe connectors, PVC pipe primer and cement, valves, and sprinkler heads. I'm sure you'll need a book or more detailed intructions to put it all together, or use trial and error and figure it out. You'll need a backflow device to prevent contamination of the water supply UNLESS your valves are several inches ABOVE GROUND, and then it isn't necessary.

Answer 3

if you go to one of the dist. of materials like 'rainbird' they'll layout your system for you if your going to but the materials from them, I used pvc 1\2 and 3\4 inch pipe here in Mich. and it works great If you've never done any plumbing 'sweating pipe' let a plumber do the tap for you.

Answer 4

first find out how deep your frost line is for the area so you know how deep to dig for the lines then call dig safe or another locating service to mark out utility lines {its the law } that may save your life ie ever dig into a live power line ........ next plot out your runs to determine your amount of pipe and sprinker heads and types etc... oh and check to make sure you dont need a backflow preventer according to local codes.... be sure to shut your water off before tapping in to it or you will have a mess as for location of tap thats another reason for dig safe...good luck and dont be afraid to call a plumber if you get stuck thats what we are paid for :}
