Needle valve, and cut into the Water main with a 3/4” x 1/2” tee. Provided a 1/4 turn compression valve. Attached on existing tubing to the fridge. Also put on a new relief valve to the water heater. Increase pressure and expansion tank, and routed the relief valve closer to the floor drain. Wishing you and your family a phenomenal year. Mark, with Southside Plumbing.
