Whale Pressure Relief Drain Valve For Gas & Elec Expanse Space Heater - AK1275

The Whale Pressure Relief Drain (PRD) Valve is an essential component of the Whale Expanse Gas and Electric Water Heater. Its primary functions are:

1. Pressure Relief: The PRD valve safeguards the water heater by releasing excess pressure that may build up during operation, thereby preventing potential damage or malfunctions.

2. Drainage: The valve facilitates the draining of water from the heater, which is particularly useful during maintenance, winterization, or when the heater is not in use.

   
   

Regular operation of the PRD valve is recommended to remove lime deposits and ensure it is not blocked. This maintenance helps maintain the heater's efficiency and longevity. 

The PRD valve is compatible with various Whale Expanse water heater models, including both gas and electric versions. It is also suitable for use with Propex heaters.
