Glow-Worm 20097340 Siphon Assembly
The 20097340 siphon assembly is manufactured to original equipment specifications for sealing integrity, material resistance, and reliable long‑term performance under thermal cycling and repeated condensate flow. Condensate handling is critical in condensing boilers because stale, acidic water — formed during combustion — can damage internal components or lead to blockages if not removed properly. The siphon assembly helps maintain an effective water trap that prevents unwanted air and gas ingress while allowing the condensate to flow freely toward the external drain. Its design also helps reduce the risk of dry traps or siphon loss due to evaporation, which can lead to nuisance boiler fault codes if gases are sensed by internal sensors.
Over time, siphon assemblies can become blocked by debris, scale, or sludge carried with the condensate, or they may lose their water seal due to evaporation or improper installation. A malfunctioning siphon can result in gurgling noises, boiler lockouts (e.g., F28/F29 fault codes), foul smells, or condensate backing up into the boiler, all of which compromise comfort and reliability. Replacing a worn or blocked siphon with this OEM component restores proper sealing and condensate disposal, helping maintain efficient, safe boiler operation. Because the correct installation of condensate components is essential for system compliance and safety, fitting should be carried out by a qualified heating engineer, who will also ensure adequate fall and drainage to prevent freeze‑ups or blockages.
