Attach foot pump to Schrader valve on expansion vessel
Attach foot pump to Schrader valve on expansion vessel
Observation:
Check the pressure of the expansion vessel.
It should be approximately 1 bar.
Even if pressure is ok use the foot pump for approx. 2-3 pumps.
If the pressure rapidly increases it would indicate a blockage in the braided hose running from the manifold to the expansion vessel.
