简介

The seal on the support valve is heavily stressed. It should always be well greased and also be exchanged from time to time. In this model, the support valve is independent of the heater, there is also a version in which it is screwed to the heater.

Note: the device is opened here to replace the seals. This is a reliable but a bit cumbersome procedure. If you are very skilled and can work carefully, you May also pull off the seals and replace them directly. Use a blunt tool, being careful not to damage the valve.

Wow! I dare anybody to follow these instruction for a successful repair. Terrible sequence and explanation. Just look at the pictures (they are good and clear) and try to figure out the rest.
