Pièce de rechange pour ensemble de tube de dérivation Baxi De Dietrich 7769934

The bypass tube assembly spare part for Baxi boilers is an essential component that helps regulate water flow within the heating system. This assembly ensures that a minimum flow rate is maintained even when some radiators or zones are closed, protecting the boiler from overheating and thermal shock. If you notice fluctuating temperatures or unusual noises from your Baxi boiler, a faulty bypass tube assembly could be the cause. Replacing this part with a genuine-style spare helps restore proper hydraulic balance and extends the life of your heating equipment. Suitable for Baxi boiler maintenance and repair.
