Non-return valve - Satellite

Check the non-return valve in the built-in satellite.

Look for dirt, deposits and worn springs and O-rings.


Check the rest of the housing for damages.

If the non-return valve fails, air and chemicals can get into the pump and cause contamination and damages.

Note! When you disassemble parts with stainless steel thread, always remember to lubricate before reassembling. Watch the video tutorial How to lubricate stainless steel thread
