TOTO TLE05701U – Frequently Asked Questions
1) What thread size are the water connections on the TOTO TLE05701U thermostatic mixing valve?
The TLE05701U uses G 1/2 inch threaded connections, which are compatible with 1/2 inch NPSM. That means standard 1/2 inch NPSM supply fittings and flex connectors thread straight on without an adapter. Note this is a straight-thread connection, not tapered NPT, so seal it with the supplied washer or gasket rather than tape on the threads.
2) Does the TOTO TLE05701U mixing valve mount above or below the counter?
Below deck. The valve is installed under the lavatory deck, where it blends the hot and cold supplies and feeds a single tempered line up to the faucet controller. Plan for clear cabinet or chase space under each sink, plus access for the stops and the check valves.
3) Will this TOTO valve work with any touchless faucet, or only TOTO?
The TLE05701U is built for TOTO touchless faucet controllers, and that is the pairing the valve is specified for. It supplies a single tempered line to a controller designed for one supply inlet. If your faucet is another brand or a two-supply mixing faucet, this is not the valve for it.
4) How does the TLE05701U prevent scalding if someone flushes a toilet on the same line?
The valve uses a Shape Memory Alloy element that reacts to changes in the incoming water temperature and adjusts the hot and cold blend to hold the setting. That is what protects the user when a pressure or temperature swing hits the supply, which is the common failure point in a multi-fixture commercial restroom.
5) Do I need to add check valves and strainers ahead of this TOTO mixing valve?
No separate ones are required at the valve. Integral check valves and debris screens are built into the TLE05701U for backflow prevention, so hot cannot cross into cold through the valve and grit is caught before it reaches the mixing element. Facility stops and any isolation required by your local code are still on you.
6) What is the TOTO TLE05701U mixing valve made of, and is it low lead?
Low-lead solid brass body. Brass is the stated product material, which matters for a potable water fixture in a school, healthcare, or government building where non-lead wetted parts are the requirement.
7) Can the outlet temperature on the TLE05701U be set, or is it fixed at the factory?
It is adjustable. The Shape Memory Alloy element allows a fixed ambient water temperature to be set, and the valve then holds that setting against fluctuation in the supplies. On a multi-lavatory job you set each valve once at commissioning and it maintains that blend.
8) What is the exact TOTO part number to order for this touchless faucet mixing valve?
Order TOTO TLE05701U. It is a single configuration, not a family with finish or size options, so there is nothing further to specify on the order line. One valve serves one touchless faucet controller, so quantity matches your lavatory count.
