installing whole house filter on outside of house
I want to install a whole house water filter, and the only the place it can go is on the outside of the house (which is a small 1 bedroom cottage). This small house has 1 bath and there is no place inside to access the main water pipe. The house sits on block foundation with a crawl space, and all the pipe connections are under the house. But that crawl space is very difficult to go in.
With a little digging, I found the main water pipe in the yard, about 10" in the ground, that goes into the crawlspace under the side of the house. The water main appears to be 1" galvanized pipe.
So my plan is not to crawl under the house and drill through the floor to create an inside connection. Instead, I'd be ok with the water filter attached to the outside house wall, right where the main pipe goes under the house from the yard.
I'm handy with tools, but rarely do plumbing jobs. Could I do this?
What I want is just one water filter, like maybe the Big Blue 10" or Whirlpool from Lowes. And a shutoff valve.
My question as a newbie plumber is making the right connections and using the right type of piping. This plan requires cutting the galvanized main in the ground! Then installing pipe to lead out of the ground and up/down the side outside wall of house to the filter.
What pipes and connectors to use in this project case? I sure hope the galvanized pipe does not need to be threaded! Can I use a Fernco coupler, and PVC for this project? Another decision I need to make is would it be best to install the filter in the ground inside one of those large sprinkler buckets (that are like meter ground boxes)? This would provide natural insulation from heat/freeze. The water filter would sit horizontal in the underground bucket.
So here are all my questions:
1. better to install the filter on outside wall of house or in the ground in a sprinkler bucket?
2. what piping to use from the main to the filter? PVC ok?
3. once I cut the galvanized main, how to connect to the new pipe? Fernco coupler ok?
