The hot water from the boiler flows using a pressure hose with elbow connector towards the drainage valve. The connector is secured with a clamp.
On older models, the hose is plugged in without a connection bracket. It is tricky to reconnect this hose during reassembly. If you want to make it easier, then buy this connection angle, it is not expensive.
Pull the clamp from the connector.
Lift the elbow connector up from the drainage valve. You may need some force.
The connector is sealed with an O-ring. The ring may remain either on the connector itself or in the drainage valve. Replace it when reassembling.
