Is it possible for a DIYer to replace an expansion vessel and hose? It's an external grant vortex boiler and from what I've seen online it looks simple enough
A Certas engineer said so at service. To be fair he didn't say he'd quote until I asked him to, which seems pretty expensive. He said it was very heavy. Does that water out of the valve check work on this model, I'm yet to check?
Do have any advice on how I could confirm what he said?
Press thge schrader valve needle and see if air or water comes out, if neither or no pressure with needle depressed, isolate the boiler or drain down system and remove the water end hose, pump up the air end (if you can) to say 1.5bar, put your hand over the water end and see if any pressure buids up even slowly, if so, the diaphragm is punctured and new EV required.
Normally the air will have droplets of water with it if the vessel has gone. Just try to recharge it and go from there. Dont forget to dump the water pressure first before pumping up the vessel.

only have one guage, water, let me get this clear, if I pump up EV and leave open the water drain tap that will drain water to zero..the close water tap and repressurise, is that about right?

a bit late tonite but on my mind?...under the boiler theres two warer controls close together I use to top the water up. The big white key is thag suposed to cut the water off, cus on or off, I can still get water tgru the small white valve. Am thinking cud the water be passing thru into system and spurting out safetg valvd cus I have heard the hiss of water a few times being ejected outside?..try to attach pic of the two valves which are side by side!
