New Project: Guest House Bathroom

New Project: Guest House Bathroom

The primary purpose of building the Hardin Access Pipeline was to allow me to build a bathroom in the guest house. Before doing the framing work for the bathroom and the utility room (which will hold the water filter, softener, and heater, among other things) I am doing some initial plumbing work. My first step was to install the whole home filter, and to install a faucet on the outside back wall of the guest house for easy hose access. The water line coming into the house terminated in a 1-inch threaded valve, so I had to use a fixture to downsize it from 1-inch to 3/4-inch, which is what would go into the filter, water softener, and water heater.


I screwed a 3/4-inch SharkBite fixture into the 1-inch to 3/4-inch downsize fixture, which would allow me to start connecting the 3/4-inch lines.


To connect the exterior faucet, I used a t-junction that downsized the 3/4-inch line to 1/2-inch line going down towards the ground, and connected it to a faucet fixture that went through the exterior wall and was fixed to a stud in the wall.


Here is the end result from the outside of the guest house:


After connecting the faucet, the next step was to connect in the whole home filter. This was pretty straightforward. I screwed in a 3/4-inch SharkBite fixture into either side of the filter, and used those to connect the filter to the 3/4-inch line. I also installed a valve downstream from the filter, so that I can shut off water coming into the house, and also cut off water after the filter before it goes to all of the appliances.



Next weekend, I’ll work on installing the water heater and water softener, which will complete the initial plumbing work for the utility room prior to framing the bathroom and utility room.
