Can a DIYer replace an expansion vessel

[Crossfingers]

I think I saw a spray of water when I first pressed. Ill check again.

Thanks

Nope, no spray. Maybe it was dust or something

Tried pumping it back up and could hear bubbles in the boiler. Time for a new vessel I think.

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.

I got same problem!
I drained water till zero on water guage, then inflated the EV, The water guage went up, shud that happen?

Keep draining while you pump up and wait until the water stops then pump some more until you have no water coming out and the shrader gauge says 1 bar

If that happens dump the pressure again, until the water gauge doesn't increase whilst pumping up the vessel.

many thanx for that, will try that tomorrow, I thought the EV had punctured and the air was leaking into the water?

No, as you pump up the ev the water inside it is pushed back into the system and can make the water gauge increase.

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?

no got it wrong u mean one bar on footpump, and zero on water guage, then add water to one bar on water guage?
