1 in x 11 in Well Pressure Tank Tee Kit with 40-60 PSI Switch

Our review of this 1 in x 11 in well pressure tank tee kit finds it best for DIY homeowners and plumbers who need a ready-made, lead-free assembly to fit tanks up to 16 in diameter. The single biggest reason to buy is convenience: the kit arrives with an 11 in tank tee with union plus a 40-60 psi pressure switch, 100 psi gauge, relief valve and drain valve, so most common installation tasks can be completed without hunting down extra parts. The review focuses on build quality, safety features and real-world ease of installation.

Key Features

• Complete kit: Includes an 11 in tank tee with union, 40-60 psi pressure switch, 100 psi pressure gauge, 100 psi relief valve and drain valve so installers get all core components at once.
• Broad fit: Designed to fit most pressure tanks with diameters up to 16 in, reducing the need to confirm multiple part numbers.
• Safety control: The 40-60 psi pressure switch automates pump on/off control to maintain consistent system pressure and reduce pump cycling.
• Overpressure protection: The 100 psi relief valve vents excess pressure to protect the tank and plumbing from damage if the switch or system fails.
• Durable materials: Brass construction provides corrosion resistance and leak-free joints while remaining lead-free for safe potable water use.
• Service convenience: The union and drain valve speed tank replacement and line draining for maintenance without disassembling the entire plumbing run.

Who It's For

This kit is aimed at homeowners replacing or installing a single well pressure tank who want a simple, mostly plug-and-play assembly that covers the common pressure control and safety items. It is also useful for handymen and small plumbing contractors who value a compact kit that fits tanks up to 16 in in diameter.

Those who should look elsewhere include users with nonstandard fittings or unusual tank sizes, and anyone who requires digital or adjustable electronic pressure controllers rather than a mechanical 40-60 psi switch. Professional installers who need custom configurations may prefer individual components chosen to match specific system layouts.

Pros & Cons

Pros

• All-in-one kit reduces parts sourcing and speeds installation.
