Kupferle offers a complete line of durable and easy to maintain post flushing hydrants and below-grade blow-offs. Our line of 2” and 4” (non-fire-rated) hydrants are excellent solutions for dead end water mains. Our self-draining, non-freezing hydrants and blow-offs are easily maintainable from above ground, with flow rates between 380 GPM to 1340 GPM depending on the model. On dead end water mains in particular, our hydrants and blow-offs are the perfect alternative to add to your specs where fire protection is not required.
