Mueller Industries h-15026n Ground Key Corporation Valve

Product Description

The MUELLER INDUSTRIES h-15026n is a ground key corporation valve designed for water service line applications. It connects a pressurized main to a service line by providing a quarter-turn shutoff at the tap point. The valve features an AWWA IP thread inlet and a Mueller INSTA-TITE IPS PE pipe outlet, making it suitable for transitions to polyethylene service pipe. Licensed plumbers and water service contractors install this valve during new service installations or service line replacements where a reliable, low-profile corporation stop is required.

The h-15026n is used in underground water service applications, typically at the main tap location. It is suited for residential and light commercial service connections where the municipality or utility authority requires an AWWA-compliant corporation stop. The INSTA-TITE outlet provides a secure mechanical connection to IPS-sized PE pipe without the need for insert fittings or compression sleeves. Available sizes are 3/4 inch and 1 inch to match standard service line diameters.

Compatibility

Installation Notes

Installation of corporation stops must be performed by a licensed plumber or qualified water service contractor in compliance with local utility standards and applicable plumbing codes. The main must be under controlled pressure or depressurized per utility procedure before tapping. Ensure the INSTA-TITE outlet connection is fully seated and torqued according to the fitting procedure before backfilling. Inspect the valve for leaks before covering the excavation.
