Worcester 24i Junior - PRV?

[Mulberry View]

Our Static Caravan has a Worcester 24i Junior combi boiler...

 

 

It's losing pressure. I re-pressurised the boiler to 1.5 bar (cold) and ran the boiler, there is water dripping quite fast out of the PRV discharge, but the system pressure doesn't exceed 2.5 bar with heating on.I'm guessing it's the PRV that's at fault? Is this it?

 

 

Any words of wisdom here? I'd be grateful... It doesn't look like rocket-science to change it?

Gas Safe plumber would be my answer.

For a PRV? When I've built a whole Nudura house without being a qualified builder?!

You don't need to be qualified to build a house in the UK.  ICF is fairly easy DIY.  It would be more impressive if you built in brick and block.

 

No requirement for Gas Safe if it is just for you but would be my preferred option.

I’m one for caution but it’s just push fit with a retaining clip. Worst thing that can happen here is you get wet tbf. 

 

Drain down, get a towel, isolate the electrics to the boiler, and get it swapped out. 
 

You'll need a lint free cloth to clean out the receptacle and some silicone grease to lube the o ring on the new item. 
 

Slight twisting motion when you offer it back in. Same retaining clip will be fine.

Have you checked the pre charge pressure in the expansion vessel?

No I haven't. What's involved in doing so?
