Boiler thermostat dump valve unpegged? (1 Viewer)

[stephsol]

Due to the present and forecasted temps of -7°c, I have removed the peg that held the valve shut (up), but, pressing the valve down did not dump any water. The question is, will it only dump when the temperature drops? It's standing in a yard at the garage waiting engine repair.
Regards
Steph

If it is this type of solenoid valve, it should have opened at around 6 degrees, unless the boiler is on and feeding it a 12v supply, whereupon it remains closed.

By applying the old clothes peg trick, and at temperatures of -7 degrees, the damage to the boiler which the valve is meant to avoid, may well already be done. Obviously, I hope you have managed to escape that expensive mistake.


Whilst waiting for some time for an engine repair/replacement, why didn't you drain down anyway?

Cheers,

Jock.

Sounds like it's frozen inside the valve already.

Yep, my thoughts too.

The clothes peg trick should never be used.
Those valves open at +5c for a reason.
Replacement of a frozen boiler comes with a comma in the price.

The far better trick to use if you need to fill your tank in the cold and before you run the heating is to;
Put a hot water bottle in the valve area.
Much safer, does not matter if it's forgotten, and it will thaw any ice already there.

Especially as its in a garage so presumably no heating on. There's a bit more needed that draining the boiler too so I hope it was drained.

As an aside, why do you keep water in the tank ?
I drain my tank after almost every use.

The only time I don't is in the summer if I know we will be using the van again within a week.

Thanks guy's,
I was full time for 7 yrs up to November 2023, and never had a problem, I was booked in for a new water pump today, as water not getting delivered to taps, so that it's mt, might be a point. I was expecting to see the water tank mt as well, the valve did compress, so although possible, not frozen. I seem to recall there was a manual dump v/v there somewhere, unfortunately I had a Taxi waiting, so I was in a hurry.
