A Tank Tee is a fitting with several contacts and accessory plug-ins, when used the installation is neat and compact. There are two line connections, one for that inlet supply line through the pump / properly, the other links towards the discharge line for the plumbing system. Four FPT accessory ports for a pressure change, pressure gauge, relief valve and drain valve get rid of the necessity for having several fittings and nipples which include clutter around a pressure tank.
Kinds of Tank Tees
Tank tees are available in different lengths brief (3”) to lengthy (16”) to work alongside the connection dimensions and locations on different brands of pressure tanks. The 2 significant design types are Union and Low-union which may be called solid or 1-piece tank tees. They come in 1” and 1-¼” with female or male tank connections. Irrespective tank tees are designed for hooking up to the pre-charged pressure tanks. Tank tee length measurements are Middle-Finish-Lengths (CEL)
Are used on pressure tanks with the tank connection protruding from the side from the tanks base. Brief tees vary from 3” to 4-1/2” CEL. Brief tank tees can be found in several types of tank link as shown below.
Lengthy Tees Tank
Are used on pressure tanks using the tank link becoming possibly in the center or offset inside the bottom of the tanks foundation. Lengthy tanks tees have men NPT tank connection and are available in several lengths. For a longer time tank tees are required since the diameter of the pressure tank chosen raises, the CEL should be sufficient to extend the tee go out far enough in order that the pressure change can threaded on or off without contacting the pressure tank.

Union vs. Non-Union Tank Tees
The advantages of union tank tees are realized throughout initial installation, and significantly cuts down on the work involved for tank substitute. A union kind tee effortlessly disconnects the old tank, which may be eliminated within a few minutes leaving all the line and item connections and wires undamaged. The brand new tank are able to be installed with all the tank tee leg from the old tank, set in position and reconnected for the tank tee brain by tightening the union. Job finished!
Union tees that incorporate an O-ring provide a dependable watertight seal off. No need to be worried about the connection leaking. It is recommended to select an excellent tank tee that uses a North American standard O-diamond ring which can easily be bought in the event a replacement is ever needed.
Low-union tank tees do the same work, are less money and spend less on the investment price. However, they just do not possess the identical easy installation and time conserving benefits especially when a tank needs to be changed. The additional labor included throughout installation or tank replacement will far surpass the primary cost savings on the tee.
Stainless Steel Tank Tees
Stainless steel tank tees more price competitive than No-Guide Bronze and they are changing bronze (red brass) tank tees because the creation of No-Guide requirements in 2014. Typically cast from 304 stainless steel which can be incredibly long lasting and very corrosion proof. Even though stainless steel tees can be more expensive than brass, they actually do not contain zinc relieving the issues with dezincification that may happen when utilizing brass alloy tank tees in aggressive water problems. An additional benefit is the very high strength of stainless steel virtually removes all probability of stress cracking when threading into female connections.
Brass Alloy Tank Tees
Brass tank tees are cheaper and therefore are suited for installs in most areas. However brass alloys2-07TK-25SF-2NL are certainly not as corrosion resistant as stainless steel, consequently installations in areas where the water is very corrosive to brass, it is recommended to update to stainless-steel.
Galvanized Tank Tees
Galvanized tees are cheaper than both stainless-steel and brass tank tees. Their use is typically07HC125G restricted to installations on galvanized pressure tanks with no bladder. Galvanized tees are chosen to get rid of the potential risk of galvanic rust among dissimilar metals. Galvanized tank tees used along with galvanized nipple and fixtures solves the situation. It is important to be aware that some plumbing rules do not allow the use of galvanized fittings and nipples, one should verify that galvanized tank tees meet each of the relevant plumbing program code requirements.
PVC Tank Tees
PVC tank tees certainly are a very competitive option in comparison to stainless, brass, and07PT-25-2 galvanized components. They may be extremely immune to rust, they might not be as durable as steel tank tees, neither are there numerous designs readily available. They may be an extremely suitable option, when proper Pvc material installation methods are implemented, the smroye of the higher-quality thread sealant mixture instead of PTFE thread sealant adhesive tape and steering clear of over tightening will reduce the potential risk of over worrying the female NPT item ports.
