I have a waterworks problem?

[colyboy]

Van has been drained down for awhile now and since half filling the tank it is reluctant to come through the taps. Cold tap open it only spluttering out, the hot tap hardly anything. I have seen on here a simple answer but cannot find it. I am sure someone will have an answer.

Sounds like the pump inlet is sucking air in... Maybe

 

[Blue Knight]

Those are the exact symptoms of when I forget to close the frost protection valve.

 

[Landy Andy]

Check frost valve is shut.

I keep a bookmark to this video handy on my phone. The frost valve trips pretty easily as soon as the temp drops. This video gives you a good talkthrough of how to set up and drain down.

look for a puddle under the van

 

[Paul and Kate]

I would say frost protection or boiler drain tap open.

 

[David and Sally]

I fill hot system first. It takes ages. Then the cold.

Sounds like :-

Frost valve open
Drain valve open.
A split union or pipe in the system - look for water leaks.
Pump has frozen over winter and is not running well - that happened to our submergible pump.

This used to happen everytime we drained down our system. At hand over the guy told us to physically shake the boiler. Worked every time. Must be an airlock

If possible have tank lower than water heater

We had a split in the plastic filter situated near the pump, I hadn’t drained it out prior to winter, it split and was letting air into the system.

It's really nice when the OP comes back to the thread to tell all involved what the problem was and thanks everyone.

Well done colyboy

 

[Trevor Wbm]

Excellent, not just me that does that then.

 

[Paul and Kate]

Excellent, not just me that does that then.

Oh I think we've all done it.
Once had a neighbour onsite ask why water was pouring out of the back of the mh.
