Pride Plumbing came out and provided cost estimates to 1) install a refrigerator ice maker water supply line (this would require us to: a) drill holes in the floor and a kitchen cabinet; b) tie a new section of PEX piping and fittings into the main water supply line underneath the home and run it up through the floor and cabinet holes to the refrigerator's location; and c) install a new water shutoff valve angle stop and connect an above-floor braided stainless steel water supply line to the shutoff valve and the refrigerator); and 2) repipe and replace the water supply lines under the house in the crawlspace, going to the fixtures in the kitchen, at the washing machine, and in one bathroom, with new PEX piping and fittings.
