Stainless Steel Pressure Tank Installation Kit: Durable and Hassle-Free Installation Solution

The Stainless Steel Pressure Tank Installation Kit is designed for superior quality and ease of use, ensuring a seamless setup for your pressure tank. Constructed from high-grade 304 stainless steel, this kit offers corrosion resistance and durability, making it perfect for long-term use in various well systems. Whether you're working with submersible well pumps, shallow well jet pumps, or deep well pumps, this comprehensive kit eliminates the need to purchase individual components, providing everything you need for a professional-grade installation.

Now Includes a Union for Easy Maintenance and Installation

This tank tee kit features a union connection that allows for quick and easy disconnection in case of maintenance or emergency. The union also simplifies installation, making setup more efficient and minimizing downtime in your water system.

Why Choose Stainless Steel Tank Tees?

Stainless steel tank tees have emerged as a top choice over no-lead bronze (red brass) since the 2014 introduction of no-lead regulations. Cast from robust 304 stainless steel, these tees offer superior durability and corrosion resistance. Unlike brass fittings, they are zinc-free, eliminating the risk of dezincification—especially important in aggressive water conditions. Their high tensile strength greatly reduces the risk of stress cracking when threading into female connections.

While stainless steel is slightly more challenging to work with and requires proper sealing techniques to prevent leaks, its advantages in long-term performance and reliability make it a smart investment. To ensure optimal sealing and reduce the risk of galling, use both P.T.F.E. Thread Seal Tape and a stainless-compatible thread compound.

Key Features: Efficient, Durable, and Safe Installation

• Pressure Switch: Field-Adjustable for Any Standard PSI Range
  Standard factory setting is 30–50 PSI, but the switch can be re-set in the field to common ranges like 40/60 PSI or others to match your system needs. Adjustment is done via the internal spring nut; turn clockwise to raise pressure and counter-clockwise to lower it. Make sure to power down the system and verify with a gauge when adjusting.
• Relief Valve: Pre-set at 75 PSI for added safety, protecting your system from overpressure.
• Pressure Gauge: Accurate gauge with a 0-100 PSI range for precise monitoring of system pressure.
• Hose Bib: Rated for up to 200 PSI and 248°F, providing high-temperature resistance and reliable performance.
• MPT Threading: Ensures secure and reliable connections with 1" or 1-1/4" MPT threading options, suitable for a variety of installations.
• Lead-Free Certification: Certified lead-free for safe use in potable water systems, meeting safety and environmental standards.

Frequently Asked Questions (FAQ)

Is the pressure switch adjustable, or is it locked at 30–50 PSI?

The pressure switch included in this kit is field-adjustable. While it ships with a factory default setting of 30–50 PSI, it can be adjusted to other common pressure ranges — including 40/60 PSI — to match your system requirements.

Can I set this kit up for a 40/60 PSI system?

Yes. No alternate switch is required.
The included pressure switch can be adjusted by changing the internal spring tension, allowing you to set standard pressure ranges such as 40/60 PSI, provided the pump and tank are rated accordingly.

How is the pressure switch adjusted?

Adjustment is done directly on the switch using the internal adjustment nut:

• Turning the nut clockwise increases both cut-in and cut-out pressure

• Turning it counter-clockwise decreases pressure
  Always power off the system before making adjustments and verify final settings using a pressure gauge.

Do I need to adjust my pressure tank when changing the pressure switch?

Yes. When changing pressure settings, the pressure tank pre-charge must be set approximately 2 PSI below the cut-in pressure.
Example:
For a 40/60 PSI setup, set the tank pre-charge to 38 PSI.

This is critical for proper system performance and to prevent short-cycling.

What type of systems is this kit compatible with?

This kit is suitable for:

• Submersible well pumps

• Shallow well jet pumps

• Deep well jet pumps

It is designed for residential and light commercial water systems using standard pressure tank configurations.

Why choose stainless steel over brass for a tank tee?

304 stainless steel offers:

• Superior corrosion resistance

• No zinc content (no risk of dezincification)

• Higher tensile strength than no-lead brass

• Better performance in aggressive water conditions

This results in longer service life and fewer failure points over time.

Is this kit safe for potable water systems?

Yes. All applicable components are lead-free certified and approved for use in potable water systems.

What safety features are included?

• Pressure Relief Valve: Factory pre-set at 75 PSI to protect against over-pressure

• Pressure Gauge: 0–100 PSI range for accurate monitoring

• Union Connection: Allows fast disconnection for service or emergency maintenance
