Plumbing & Water Heater Parts

Repair parts for residential plumbing and water heaters, quoted by size or the marking on the part you are replacing. Some water-heater and gas-line work requires a licensed plumber under state and local rules. Brand names, when used, are compatibility only — we are not an authorized dealer for those makers.

FAQ

What information do you need for a water-heater part?

The heater's model number, plus the marking on the failed part (for example, valve rating or element wattage). A clear photo of the label helps.

Do you sell water softener salt?

No. Pallet salt is excluded. We quote filter cartridges, RO membranes and related water-treatment consumables in the water filter category.

Are these authorized brand replacements?

No authorized-dealer claim is made. We source compatible or specified parts and label fit by size or model.
