More About Watts 3L & 53L Pressure Relief Valves
Series 3L and 53L are used for protection against excessive pressure on domestic storage tanks or tankless water heaters. Similar in construction to Watts Model 10L, the Model 3L has no temperature relieving element. Model 53L has the basic design as Model 3L except it is furnished in 1/2" (15mm) size and does not comply with A.S.M.E. requirements.
