Pros
- Comprehensive kit includes everything needed for a pressure tank installation or upgrade.
- Solid brass construction ensures longevity and resistance to corrosion.
- User-friendly design with threaded connections and a union for easy assembly.
- Consistent high ratings from customers highlight its quality and value.
- Safety relief valve and drain valve add peace of mind and convenience.
Cons
- The relief valve ships unset and requires manual adjustment to 75 psi before use, which may be confusing for some users.
- Installation is recommended only after checking existing plumbing; not a simple plug-and-play for everyone.
- The included pressure switch is pre-set to 40-60 psi, limiting flexibility for systems requiring different pressure ranges.
The Miumoon 1"x11" Well Pressure Tank Tee Kit is a comprehensive package designed for homeowners and DIYers who need to install or replace a well pressure tank. It combines all the essential components: a brass tank tee, 40-60 psi pressure switch, 100 psi pressure gauge, pressure relief valve, drain valve, and ball valve. This kit is ideal for anyone looking to upgrade their well system or perform a maintenance swap without sourcing parts separately.
Out of the box, the standout feature is the all-in-one convenience. The brass tee is sturdy and corrosion-resistant, promising long-term reliability. The pressure switch automatically controls the pump, and the relief valve adds a critical safety layer by releasing water if pressure exceeds safe limits. Customers consistently praise the ease of installation and the quality of the materials, noting that the union connection simplifies alignment.
In real-world use, the kit performs as expected. The 11" tee fits most standard pressure tanks up to 16" diameter, and the threaded connections (1" NPT male, 3/4" NPT female) are compatible with common plumbing. The included ball valve and drain valve offer practical convenience for system isolation and maintenance. However, be aware that the relief valve comes unset and must be adjusted to 75 psi; this is clearly stated but can be an extra step for those who prefer a ready-to-use product.
Build quality is a highlight. The brass components feel solid and are lead-free, making them safe for drinking water. The gauge provides clear readings, and the switch operates reliably. A minor drawback is that the pressure switch is fixed at 40-60 psi, so if your system requires a different range, you'll need to swap it out. Also, the manufacturer recommends checking existing plumbing before installation, which is standard but worth noting.
Final verdict: The Miumoon pressure tank tee kit offers excellent value for its price. It bundles premium materials and essential components into one package, saving time and hassle. While the valve adjustment is a minor inconvenience, the overall build and performance earn it a strong recommendation for DIY well system projects.

Below is a quick comparison of the four Miumoon kits. Each includes the same high-quality brass tee, 100 PSI gauge, and drain valve. The main difference is the pressure switch setting, which we’ll help you choose in the buying guide below.
Buying Guide: Choosing the Right Pressure Relief Valve Kit
1. Pressure Switch Setting: 30/50 vs 40/60 PSI
The pressure switch controls when your well pump starts and stops. A 30/50 switch activates the pump at 30 PSI and deactivates at 50 PSI. A 40/60 switch operates at higher pressures, turning on at 40 PSI and off at 60 PSI. Your choice depends on the pre-charge pressure of your tank and your household’s water demand. Most standard residential systems use 30/50, but larger homes or those with higher water usage may benefit from 40/60. Miumoon offers both options in their kits, so you can match your system exactly. For more on pressure systems, visit our Pressure Systems category.
2. Relief Valve Adjustment: A Critical Safety Step
All Miumoon kits ship with the relief valve unset. This means you must adjust it to 75 PSI before connecting the kit to your system. Why 75 PSI? It is the safe pop-off pressure for tanks rated at 100 PSI or higher. Turning the adjustment screw clockwise increases the pressure; counterclockwise decreases it. Use a pressure gauge to verify the pop-off point. Never skip this step: an unadjusted valve could fail to open during an overpressure event, leading to tank rupture or plumbing damage. Visual learners can find online tutorials, but the target is always 75 PSI.
3. Material and Build Quality
The tee in these kits is machined from high-quality brass, which resists corrosion and ensures a leak-free connection. It is also lead-free, making it safe for potable water systems. The included pressure gauge reads up to 100 PSI, and the drain valve simplifies maintenance. Miumoon backs their products with a satisfaction guarantee, so you can install with confidence. For more on well pump components, see our well pump for pressure tank.
4. Kit Completeness: Everything You Need in One Box
Each Miumoon kit includes an 11-inch tank tee with union, a pressure switch, a 100 PSI pressure gauge, a 100 PSI pressure relief valve, and a drain valve. The union allows easy removal of the tee for future servicing. Both ends of the tee have male 1-inch NPT and female 3/4-inch NPT threads, fitting most tanks up to 16 inches in diameter. This all-in-one package saves you the hassle of sourcing individual parts. Just check your existing plumbing for compatibility before installation. For a broader selection, read our well pump kit buying guide.
5. Compatibility with Tank Sizes
These Miumoon tee kits fit most pressure tanks with diameters up to 16 inches. The 11-inch tee with union accommodates standard tank openings. Always measure your tank’s inlet size and thread type before purchasing. The kit’s male 1-inch NPT and female 3/4-inch NPT threads cover the most common configurations.
6. Ease of Installation
Installation is straightforward: remove the old tee, apply thread sealant, and screw in the new kit. The union allows you to rotate the tee for optimal alignment. The included drain valve makes future maintenance simple. Most DIYers can complete the job in under an hour. For more installation tips, see our complete well pump kit guide.

Frequently Asked Questions
What is a pressure relief valve for a well pump?
A pressure relief valve is a safety device that automatically releases water when the pressure inside the tank exceeds a safe threshold. It prevents damage to the tank, pump, and plumbing. In Miumoon kits, the relief valve is adjustable and must be set to 75 PSI before use. This simple step can save you from costly repairs.
How do I adjust the pressure relief valve on my well pump?
Locate the adjustment screw on the top of the relief valve. Turn it clockwise to increase the pop-off pressure or counterclockwise to decrease it. Use a pressure gauge to verify that the valve opens at exactly 75 PSI. Ensure your tank is rated for at least 100 PSI. For more on pump installation, see our guide on choosing the right pump.
What is the difference between 30/50 and 40/60 pressure switches?
A 30/50 switch turns the pump on at 30 PSI and off at 50 PSI, while a 40/60 switch operates at 40-60 PSI. The choice depends on your tank’s pre-charge and water usage. Miumoon offers both options in their tee kits. For typical residential systems, 30/50 is common; larger households may prefer 40/60.
Can I install a pressure relief valve kit myself?
Yes, with basic plumbing skills and tools. The Miumoon kit is designed for easy installation, with threaded connections that fit standard tanks. Always turn off power and drain the system before starting. Check local codes and consider consulting a professional if unsure. For step-by-step advice, refer to our well pump kit buying guide.
How often should I replace the pressure relief valve?
Pressure relief valves should be inspected annually and replaced every 3-5 years or if they show signs of leakage or corrosion. Regular checks ensure they will function when needed. Miumoon kits include a durable brass valve that lasts for years with proper maintenance.
