Andy,

There are two issues that I can think of. First you normally need a
high pressure pump for the required pressure to drive the sprinkler
system and second you should install a one-way valve to ensure the pump
will not pump water that's sat in the yard lines back into your home
supply lines. That's required by code in most places.

I am installing a sprinkler system in my yard in Colorado. I am about
ready to tie it into the main line under the house and run it out the
front and back of the house. Is there anything special I should do
when going through the wall?? I'm thinking:

Dig down in the dirt 1 foot outside where I want it to come through.
Drill a hole through the brick, feed copper pipe out. Fill area around
pipe with silicone. Burry pipe.

It will definately freeze in colorado in the winter, so I'm planning on
having a shuttoff valve under the house and will drain it in the
winter.

Thanks

Andy



A Pump? never heard of one.
