Dumpster dive diverter valve

This brings back memory's of my younger days, we lived in flats that was heated and hot water from a boiler building that supply all the flats. the may have been a water flow sensor on each rad pipe and hot water pipe within the flat that was connected to a token meter to pay for amount used. i steamed the security tape off the cover and removed the cover, opened the valve and placed a 2 pence in the spring area to keep the valve open, did it with both of them for rad and hot water. i had free heating and hot water all year round for 5 years. before i moved out of the flats i removed 2p's to find that the valves has seized open. The engineer checking meter to see all was good with it before we moved put it down as a valve fault as they was seized open. all was good.

Or maybe leaking and kept for the actuator.

The olive will be swaged onto the pipe from which the valve was removed, it must have been swapped out but then found to be not at fault.

I worked at a heating spares trade counter and Honeywell kit was well respected. Much of the stock was dusty as I guess it didn't go wrong that often. We never had any warranty returns. Many good brands like Grundfoss (water circulating pumps) and Danfoss too.

In many parts of the US, heating and hot water are separate because the most common heating system is forced hot air. In some areas you still find many older systems with radiators (e.g. "forced hot water") and hot water being provided by a heating loop off the boiler. The water is kept separate, but there's only one burner, in the boiler.

It's strange seeing how systems in the UK work. Here in the US the heating and hot water are separate. And the heating is just gas heating air that is circulated.

You're probably right. It was most likely a straight swap.

I'm guessing the reason there's a new olive and a new nut on there is because the olive and the nut was probably captive on the old pipe installation and so they just screwed the new valve onto the old pipe with the old olive and the old nut and put the new nut and the new olive on the old valve. That's what I would have done.

Although available here we don't use screw on connectors. The devices in the video were closed end crimps.

What an interesting little thing. The micro-switch's jacket, and the simplicity of the whole thing must have taken a while to engineer down to its lowest cost.

But you have enough stuff to deal with. Lol ;) I can imagine Ralfy opening the van to find it full of PC's.

Simon Hopkins

Delicious! I 'm home from work today and the coffee is good and hot. You always know when to brighten things, dude thanks!

Michael Thompson

Those wire ends look like they were in wire screw nut caps or butt connectors and not highly mangled. I keep both on my bench for quick wire connections that don't need long term stability.

Ryan Coleman

Was it faulty switches, or was the actuator tab not quite making it?

Big Clive

I had to replace a couple of these recently ‘cos the microswitches no longer reliably activated at the end of travel.

Shira Wolven

They are very well made. Just think how many times they open and close. Thanks for that interesting tear down.

One thing in common; finding history of some sort just discarded.
