Glow-Worm 20014169 Bypass - Genuine Glow-Worm Product\n\nAs a genuine Glow-Worm spare part, the 20014169 bypass is manufactured to precise OEM specifications for hydraulic performance, dimensional accuracy, and material resilience. This ensures that the valve opens and closes at the correct pressure differentials, providing dependable internal circulation without introducing noise, cavitation, or flow instability. Bypass valves are essential in modern boilers because they balance the internal and external flow paths \u2014 without a functioning bypass, a boiler may experience pressure peaks, pump strain, frequent cycling, uneven heating distribution, or nuisance safety lockouts due to perceived high pressure.\n\nOver time, bypass valves can become partially blocked by sludge, limescale or debris transported in the water circuit, or they can seize or wear due to repeated thermal and mechanical stress. A malfunctioning bypass can lead to symptoms such as unusual noises from the hydraul.
