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.

Buying Guide: How to Choose the Right Tank Tee for Well Pump
Match the Tee Size to Your Tank Inlet
Most residential pressure tanks use a 1-inch male NPT inlet, and kits like the Miumoon 1″x 11″ Well Pressure Tank Tee Kit are designed for that standard. If you have a high-capacity tank, the 1.25 x 14 Tank Tee Installation Kit w/UNION provides a larger flow path. Always measure the tank inlet before you buy.
The Miumoon kits include an 11-inch tee with a union, which simplifies removal during future maintenance. The larger 1.25-inch kit from the same category also comes with a union and is lead-free brass. For a full replacement, the replacement parts category on this site has more options.
Pick the Right Pressure Switch Range
Well pump pressure switches typically come in 30/50 or 40/60 PSI settings. A 30/50 switch works well for average household demand, while 40/60 delivers stronger pressure to showers and appliances. Many tank tee kits, including the Miumoon 1×11″Well Pressure Tank Tee Kit, include the switch already mounted.
If your home currently uses a 40/60 switch, choose a kit like the Miumoon 1″x 11″ Well Pressure Tank Tee Kit with 40-60Psi to keep the cut-in and cut-out points consistent. The FSG2 pressure switch in the 1.25-inch kit is also available in 30/50 or 40/60, so you can match your system. When in doubt, look at your current switch label. You can also learn more in the pressure systems guide.
Check for Lead-Free Brass and Safety Valves
Drinking water safety depends on lead-free materials, so look for brass tees labeled no lead. The kits from Miumoon use corrosion-resistant brass that should last for years. The 1.25 x 14 Tank Tee Installation Kit w/UNION also lists lead-free brass as a key feature.
Every tank tee for well pump setup needs a 100 PSI relief valve to prevent overpressure. Note that several Miumoon kits ship with the relief valve unset, so you must adjust it to 75 PSI before assembly. That single step protects your tank and plumbing from damage.
Consider Extra Components for Easier Maintenance
Some tank tee kits include only the essentials: tee, pressure switch, gauge, relief valve, and drain valve. Others add a ball valve and check valve, which let you isolate the tank and stop backflow. If you plan to service your pump often, extras like these are worth it.
The Miumoon 1″x 11″ Well Pressure Tank Tee Kit with 40-60Psi Pressure Switch, Ball Valve includes a ball valve and check valve, while the 1.25-inch kit rounds out the package with a brass boiler drain and thread tape. For more context on system design, read our well pump for pressure tank guide.
Final Thoughts
For most homes, the Miumoon 1″x 11″ Well Pressure Tank Tee Kit is the most balanced choice, combining a solid brass tee, 40/60 switch, and all essential safety components. If you have a larger pressure tank or need a heavier-duty build, the 1.25 x 14 Tank Tee Installation Kit w/UNION is the more substantial option. Measure your tank inlet, confirm your switch range, and you’ll have a reliable installation.
Frequently Asked Questions
What size tank tee do I need for my well pump?
The most common size is a 1-inch NPT tee, often sold as a 1″ x 11″ kit. If your pressure tank has a larger inlet, you may need a 1.25-inch tee like the 1.25 x 14 Tank Tee Installation Kit w/UNION. For more details, read our well pump kit with pressure tank overview.
How do I adjust the relief valve on a new tank tee kit?
Several Miumoon kits ship with the relief valve unset. Turn the adjustment screw until the valve pops at 75 PSI, which is safe for tanks rated at 100 PSI or higher. Confirm the setting before you pressurize the system.
Can I use a 40/60 pressure switch on any tank tee?
Yes, as long as the tee has 1-inch NPT ports and your pump can handle the higher pressure range. A 40/60 switch is a common upgrade for homes that need stronger water pressure. If you’re also upgrading your pump, consider a well pump with soft start to reduce startup stress.
Is a brass tank tee better than plastic or galvanized steel?
Lead-free brass is corrosion-resistant, leak-free, and safe for drinking water, making it the best material for a tank tee for well pump. Plastic can crack under cycling pressure, and galvanized steel tends to corrode. Brass also holds threads better, so sealant is less likely to fail.
