Sprinkler System - New Back flow preventer

[electronman1729]

Anyone do sprinklers? I need a hole cut in the side of my house so a new back flow preventer can be piped up.

Yes it's required by code and is really good idea for your safety.

Just need the whole drilled, or the whole thing done? Also will it be through the foundation or through the siding of the house?

I already have a hole drilled for my old spigot which is 1/2", i just need a bigger hole drilled and the back flow preventer mounted out side

go rent a hammer drill at the rental yard ($20?) with a 1" bit

Can you sweat copper? (solder)

if so, you too can install a backflow preventer

Bump
Anyone know of a good company?

When you get to the actual piping portion of the backflow preventer - you might want to consider using Shark Bite type connectors (there are several brands out there). I had one backflow preventer freeze and crack (even after the usual fall system blow out) and decided to use these so I could completely remove the assembly during the winter months. They aren't cheap but they are fast and easy to use if you aren't comfortable sweating copper pipe.

They also rattle loose and won't seal after repeated installation.

If you want to do this get unions, the correct fitting for the job

I use the same thing on mine, been set up with those the past 3 years, no issues at all with it coming loose or failing to seal.

I've had my Febco 1" PVB setup with them for 3-4 years now too and no issues. They may have even been the (crappier?) ones from Lowes. They are both on the vertical pipes in/out side so it's simple to pull and install every year. I make sure the pipes are cleaned up first. Damn old bevel unions always leaked on me, and I've had ball valves crack even after blow out.
