A water supply and shutoff connection gives a new appliance a clean start on its water: a stop valve you can close, and a line from that valve to the appliance's inlet that is new, the right length and made for the job. It applies to refrigerators and freezers with a dispenser or an ice maker, built-in and freestanding ice makers, steam ovens that plumb in, dishwashers and dish drawers, and washers. The existing valve is tried first. An old multi-turn valve that will not close fully, or a saddle valve clamped onto a copper pipe, is noted and, where it can be done at the existing stub, replaced with a quarter-turn stop; moving or adding a water line inside the wall is a plumber's work. Lines are braided stainless or copper as the maker asks, never cracked plastic tubing carried over from the old unit. Washer hoses are new, with their rubber washers seated. A refrigerator or ice maker line is flushed through before it is connected, to clear air and loose particles, and any new water filter is flushed as the manual describes. Then the valve is opened slowly, every joint is dried and watched under pressure, and the appliance is filled once while the connections stay in view. How the visit goes ### What it usually costs Low · New supply line and quarter-turn stop for a refrigerator, ice maker, dish care machine or laundry pair, flushed and tested under pressure One braided line onto a valve that already works is a short job. Replacing a saddle valve, a long run to an island or two machines with hot and cold hoses each takes a little longer. ### Answers 4 problems Water Leak After an Install: Close the Supply Valve First Ice Maker Not Filling After the Install: Valve, Line and Patience · Water Hammer After a Hookup: Banging Pipes When a Valve Shuts · Appliance Installation Code on a New Unit: Setup Modes and Hookup Messages ### Comes up most on Cold storage Dish care · Laundry ### Codes that lead here F12 · F11 · E17 · E18 Asko F12: water inlet on a dish care machine. ## Water supply and shutoff connection, step by step.

A saddle valve clamps onto a pipe and pierces it with a needle. Its packing and its rubber seal age, and it often weeps or clogs. Many plumbing codes no longer accept it, and a quarter-turn stop is the better choice. ### Why is the new line flushed before it is connected? New and disturbed lines hold air and loose bits of scale. Running a few quarts through a bucket first keeps that out of the inlet valve and the filter, and the first ice or water tastes better. ### Are braided hoses on the laundry machine enough to prevent a flood? They resist bursting far better than plain rubber, but they still age. Closing the valves when you are away for a long time, and a leak sensor on the floor behind the machine, add protection. --- **[Read on the site: Water Supply and Shutoff Connection](https://applianceinstallation.center/services/water-supply-and-shutoff-connection/)** **[Book a visit with ApplianceInstallation.center](https://applianceinstallation.center/schedule/)**
