Watts 190482 – Frequently Asked Questions
1) Is the Watts 53L 0190482 a T&P valve, or pressure only?
Pressure only. The 53L 0190482 is a poppet type relief valve with pressure protection, set at 150 psi, and it carries no thermostat or probe. If your water heater tank tapping requires a combination temperature and pressure relief valve, this is the wrong part, since it will not respond to an over-temperature condition, only to overpressure.
2) What thread connections does the Watts 0190482 relief valve have?
Inlet is 1/2 inch male NPT, outlet is 1/2 inch female NPT. So it threads directly into a 1/2 inch female tapping on the heater or tank, and the discharge tube screws into the outlet with a 1/2 inch male NPT adapter or nipple. No bushing needed if your tapping is already 1/2 inch.
3) What temperature and pressure limits does this Watts bronze relief valve work within?
Set to relieve at 150 psi, with a maximum operating temperature of 210 degrees F. The bronze body suits potable hot water service on water heaters. Steam discharge capacity is rated at 15,000 BTU per hour.
4) Does the Watts 53L relief valve have a manual test lever?
Yes, a test lever is included, so a maintenance tech can lift it periodically to verify the seat is free and the discharge line is clear. That is the routine check most facilities and multi-family properties run on relief valves.
