Appliance Installation

Have ready

Clear the path from the door to the opening and empty the cabinet under the sink before the visit. Have the model number, the manual, and any cord, whip, or hose kit that came in the box set aside. Pull the old unit out far enough to see the floor behind it if you can. We look first at the shutoff valve under the sink for the hot supply, the drain connection point at the disposal or the wye, and the receptacle or hardwire junction behind the unit. Then we measure the opening against the machine.

• Level the unit
• Water and drain connections
• Electrical whip or cord
• Test cycle

The visit

A dishwasher visit starts at the shutoffs, not at the kickplate. We check that the hot supply is actually hot, that the drain loop is high enough to stop a sink backup from entering the tub, and that the unit is level so the door does not walk open. Laundry hookups get a new pair of hoses if the ones on the floor are the original rubber.

The failure we see in 1990s Ocean Township kitchens is a plastic drain hose shoved into a disposal without the knockout removed, or a supply valve that crumbles when we turn it. We replace the valve before we slide the machine in, not after it leaks on the new floor.

Permit

Replacing a dishwasher, disposal, or laundry pair on existing connections normally needs no permit in New Jersey. Work stays in the same footprint and does not alter the drain or the circuit. If we extend a circuit, add a new receptacle, or relocate a drain or vent, that is electrical or plumbing work that does fall under a permit, and we say so before anything is opened. We do not guess at what your town wants; we ask.

On the Shore

Shore humidity is hard on the parts nobody sees. The steel cabinet base of a machine in a damp garage or a first-floor laundry rusts from the floor up, and rubber supply hoses go brittle and start weeping at the ferrule long before they burst. Braided stainless hoses and a metal-braided drain line hold up better here. We want the dryer vent short, clean, and dampered so it is not pulling damp outdoor air back in.

When we leave

Every unit gets run before we pack up. The dishwasher gets a full cycle with the door watched for leaks at the supply, the drain loop, and the disposal connection. A washer gets a fill and a spin in both directions. A disposal gets water and a load of ice, and we check that the knockout is out and the trap is not dripping. We dry the floor, confirm the unit is level, and leave the shutoffs open and the machine in place.

Built with

Braided stainless supply hoses with a burst rating, a new drain hose with a high loop or an air gap where the code calls for one, and a cord or a flexible whip sized to the unit. We use a new shutoff valve when the old one is stiff or weeping, a fresh P-trap or tailpiece gasket, and stainless clamps instead of the crimped band that came in the box. Small parts are where the callbacks live.
