I am moored on the Grand Union near Hemel Hempstead. I'm looking for someone to fix my Eberspacher preferably not too far away as I don't fancy dismantling it myself.
It does heat the water and central heating but makes a loud whistling noise.
I have used my bike pump to put air into the expansion tank and, up to now, the pump is working as it should, ie it turns off after I've used a tap.
I did this last night and my neighbours can't see how this has been the fix. Any ideas?
The new PRV is 3psi as the previous one.
I've had the boat a year and it's only just started to happen.
The pump has been replaced as it states it was manufactured in 2014. The boat is 10 years old.
The pump is a Shurflo Trail King 10 and is 30psi.
After turning off a tap the water pump does not switch off and pumps out water via the overflow pipe into the canal. Consequently I have to switch the water pressure switch on/off when I need to put a tap on.
It has suggested that the PRV may be faulty so I have replaced it and has made no difference.
Could the water pump or the expansion tank be the problem please?
