Watts 556008 – Frequently Asked Questions

1) Will the Watts 0556008 T&P relief valve thread into a 1 inch tapping on my water heater?
Yes. The Watts LF40L 0556008 has a 1 inch male NPT inlet, so it threads into a standard 1 inch female T&P tapping on a water heater. The outlet is 1 inch female NPT, which is where you run the discharge tube.
2) At what pressure and temperature does the Watts 0556008 relief valve open?
It relieves at 150 psi or at 210 degrees F, whichever condition hits first. That 150 psi setting is the fixed relief point on this model, and it reseats automatically once conditions drop back into range.
3) Is a 150 psi T&P valve right for my water heater, or do I need a lower setting?
Match the valve setting to the tank's rated working pressure. The Watts LF40L family covers 75 to 150 psi, and 0556008 is the 150 psi version. If your heater's nameplate lists a lower maximum allowable working pressure, you need the LF40L in that setting instead, not this one.
4) How deep does the thermostat probe go on the Watts 0556008, and will it reach the water in my tank?
The copper thermostat probe is 4 inches long, which is the extension version intended for tappings where a short probe would sit in insulation instead of water. On a heater with a thick jacket or a tapping in the side, the extended probe is what gets the sensing element into the hot water so the valve trips at 210 degrees F when it should.
5) What BTU rating does the Watts 0556008 T&P valve cover, and will it handle my commercial heater?
Size it against your heater's input. The pressure discharge capacity is 2,134,000 BTU per hour and the temperature (steam) discharge rating is 500,000 BTU per hour. The temperature figure is the one that governs on a water heater, so the heater's input must not exceed 500,000 BTU/hr.
6) Is the Watts 0556008 lead free for potable water?
The body is lead free bronze, which is why it carries the LF prefix in the LF40L series designation. That is the construction required for potable water service in jurisdictions enforcing lead free plumbing rules.
7) Does the Watts 0556008 have a test lever for annual maintenance?
Yes, it has a manual test lever. For property managers running a PM schedule, that is what lets a tech exercise the valve on a tank without pulling it, and it is the feature inspectors look for on a water heater T&P.
8) Does this Watts valve protect against both overtemperature and overpressure, or just pressure?
Both. It is a combination temperature and pressure relief valve, not a pressure-only relief. If you only need pressure protection on a closed system without a thermal source, a straight pressure relief valve is the correct part instead.
9) Is the Watts 0556008 made in the USA?
Yes, country of origin is the United States, which matters on public and institutional jobs carrying domestic sourcing requirements.
