Sucking AIR

[Softus]

The trouble with that arrangement Chris is that people are prone to shut off rad valves, whereas they tend to leave gate valves alone.

 

[chrishutt]

Fair point softus, but what if one or two rads had two lockshield valves? Of course an ABV would remove any doubt about it and they're not that expensive, so that's the reliable solution.

She (the boiler) is working a treat

I Have a question about about 3 way valve

Can you buy different arrangements Like below as type 2 would save me a lot of pipework issues



From previous drawings i want to T it below the pump and into the feed to the hot water tank

Was not sure wether to open a new thread or continue with this one

Can't you just rotate it 90 degrees? Then a minor pipe alteration is needed to bring the upper pipe beack down to the B port as per example 1.

 

[PCDOCTOR]

How about this

[Dan Robinson]

Or even 180 degrees

 

[PCDOCTOR]

Dan

Don't care what the locals say your a good egg

In brief does port "A" go to the top pipe feed to the Hot water storage or to the bottom pipe

Plus do i have to stop using one of the 2 pipes as it looks like it defeats the object of the 3 way valve

I do plan to fit the automatic by-pass control valve at the same time as this work between the pump and the 3 way valve

Hope this makes sense

Mr Honeywell gets VERY cross if his valves are mounted in such a way that water leaking out of the valve connections or (heaven forbid!) the shaft seal on the valve itself, can run down into the actuator.
(Unfortunately, actuators of this type are NOT even slightly water-resistant.)

 

[PCDOCTOR]

Good point

Yes shall rectify that to keep Mr Honeywell happy

Fair point softus...

Wasn't payin attention


Oh, by the way, Port B goes to hot water...

Dear all

Going to fit Automatic bypass valve tomoz as show below

Will it be OK to shut Gate valve 3 after install

 

[Dan Robinson]

Why not just change valve three for a DU144?

 

[PCDOCTOR]

Yes but no but

Local merchants did not have one in stock but did have right angled version which means a bit of pipe work but nothing serious

I'm easy all the info i find around shows it fitted just after the pump

Thinking as it is 22mm go with the flow instead of adapting to 15mm

What your thoughts

Carry on as planned and shut valve 3 or stick it in valve 3 position

Where in this have you stuck the diverter valve?
