Makes filling easy
20 May 2024  |  Tom

As I already had another safety valve fitted to the boiler, I could fit this in place of the original and benefit from easier filling of a hot boiler. Quick and easy ordering very prompt dispatch, good service.

Top up valve
09 October 2023  |  Roger

I purchased a top up valve from yourselves to fit on my Mamod traction engine as I have upgraded the burner that now far outlasts the water. It was easy to install replacing the whistle it has made a big difference to the running as the water is replaced a little at a time till the gas runs out a recommended improvement

Good Useful Item

This item is a very useful wayt of toping the water up in the boiler on the move. very useful in the older mamod locos as they have a smaller boiler then the new locos and run out of water in about 15 mins.
