Watts 11086 – Frequently Asked Questions
1) Is the Watts 0011086 a T&P valve or pressure-only relief?
Pressure only. The Watts 3L series 0011086 is a poppet type pressure relief valve with no thermostat probe, so it protects against overpressure but will not dump on high water temperature. If your water heater tank tapping requires a combination temperature and pressure (T&P) valve, this is the wrong part, you need a T&P with a probe. The 0011086 is commonly used on a side or auxiliary tapping where pressure protection alone is called for.
2) What size and thread does the Watts 0011086 relief valve need?
Inlet is 3/4 inch male NPT and the outlet is 3/4 inch female NPT. It threads into a 3/4 inch female NPT tapping on the tank or line, and the discharge pipe screws into the outlet. Run the drain line in the pipe size the outlet gives you, 3/4 inch, and do not reduce it.
3) What is the maximum working pressure and temperature on this Watts brass relief valve?
The 0011086 carries a 150 psi maximum working pressure and a 210 degree F maximum temperature. Body is brass. The published pressure range for the 3L series spans 75 to 150 PSI; this particular valve is the 75 psi setting within that range.
4) What relief capacity does the Watts 0011086 have?
Pressure steam discharge capacity is 200,000 BTU per hour. Size the valve against the input rating of the heater or vessel it protects, the valve has to be able to relieve at least as much energy as the heat source can put in.
5) Does this Watts relief valve have a manual test lever?
Yes, the 0011086 comes with a test lever so the valve can be manually lifted off its seat to verify it is free and not seized by scale. For MRO and facility crews running an annual exercise routine on water heater relief valves, that lever is what makes the check possible without pulling the valve.
