Don't Get This Wrong! Vaillant 937/938 Shunt Pump Change

Описание: Don't Get This Wrong! Vaillant 937/938 Shunt Pump Change

The Vaillant ecoTEC Plus 937 and 938 are unique boilers because of the integrated storage tank on the back—and that means they have a shunt pump that many engineers overlook or struggle to access.

In this video, I’m showing you the step-by-step process of replacing the shunt pump correctly.

I'll cover:
How to identify the shunt pump vs. the main pump
The correct way to drain the storage tank side safely
Avoiding the common pitfalls that lead to a flooded casing

Have you ever been caught out by the layout of these storage combis? Let me know your tips or your horror stories in the comments!👇🏽

Thank you all for tuning in again, I appreciate it as always!

Enjoy the video!
