air in hot water

[david_374315498]

when you turn your hot tap on for the first time it spits air for a few minutes which i no is normal, but after a few hours when you want to use the hot tap again you have to go through this process again,as if the water is running back and i noticed when i disconnect the outside water pipe a small spray of water sprays out.can any one help with some advice

Put a non-return valve in the pipe.

I used to have the very same problem with my water system. I found out it was the connector that plugs into the van that was cracked. After I renewed the connector all my problems disappeared. Ken
