Product details
The Raypak 013793F is a by-pass spring drain valve with a 1/8 in. NPT thread, for the metal heat exchanger on Raypak professional gas pool heater models 266A, 336A, and 406A.
What it does
The by-pass spring drain valve opens to drain water from the heater metal heat exchanger, a step used when winterizing or servicing the heater. Draining the heat exchanger before cold weather helps prevent trapped water from freezing and cracking it.
Fit and compatibility
This valve fits Raypak professional gas pool heater models 266A, 336A, and 406A that use a metal heat exchanger, and it threads into a 1/8 in. NPT port. It carries UPC 840891030584 and Raypak part number 013793F.
Before you order
Confirm your Raypak heater model is 266A, 336A, or 406A with a metal heat exchanger before ordering, since other Raypak heater models use a different drain valve. The Raypak 013793F is sold individually.
