Siphon-Schlauch 35 – 70 De Dietrich 7878832

The siphon hose 35-70 is a flexible tube used in condensing boilers to drain condensate from the flue system. It connects the siphon to the drain, ensuring safe removal of acidic water. Designed for boiler models in the 35-70 range, this hose is critical for proper condensate flow. Over time, hoses can become brittle or clogged, leading to leaks or blockages. Replacing with this siphon hose helps maintain efficient drainage and protects your boiler from damage. It is a simple yet important part for routine boiler maintenance.
