Re: water pressure problems
You might just have a small diaphragm pump. Some of these will mimic air in the line due to the on/off nature of the water flowing through them. It could also be that the pump is getting hot from the hot water flowing through it, not a pump problem.
Try running it with cold water, if it still overheats, you probably need a new pump.
