alpha cb24x hot water

[giarc00007]

going later today to check boiler. customer saying hot water downstairs but only lukewarm upstairs. im thinking diverter, as its obviously switching because its getting lukewarm upstairs. wonder what you guys think?

Check the actuator on the diverter valve to see how far it's pushing the pin 🙂

will check. presume pin is making contact as customer says boiler lights and stays alight whilst upstairs tap is open.

The actuator pushes the pin on the diverter valve to change the priority from heating to hot water. I was looking at one yesterday that clicked on to hot water but because the pin on the valve body wasn't being pushed far enough in the hot water was tepid at best.
Good luck dude 🙂

Diaphragm and/ or flow switch!

Diaphragm and/ or flow switch!

thanks alpha man. could it still be flow switch if they are getting warm water. i thought if switch was faulty they would get nothing?

Are they taking the temperature from the bath tap on full flow

basin full flow, bath is also same. by the way no mixer taps so i know its not cold entering hot side.

Sadly it could be either, I'd replace both and have done with them for a while!

So pin is lifting and microswitch is working,but theres a few other things it could be,check temperature at a low flow rate

will do, i did ask to try turning tap down to see if it would alter temp but she got back to me saying it was same. what else are you thinking glenno1?
