The Story
Grundfos 595926 — Replacement Comfort Valve for UP Comfort Series
The Grundfos 595926 Comfort Valve is designed to work with UP Comfort Series circulator pumps (such as UP15-10 SU7P/TLC), serving as a thermostatic crossover valve that ensures hot water is quickly available at distant fixtures. This valve is typically installed under the sink at the fixture farthest from your water heater to reduce cold water wastage and maintain hot water presence.
