Leaky Gledhill expansion relief valve

[diy_massacre]

Hi

I have a leaky Gledhill expansion relief valve block a little like this one with the same spec 3bar on the black input and 4.5 bar on the red expansion relief value. It protects a 250L Gledhill unvented tank. All the input pipes have isolation valves so pretty easy to exchange components

How much should it cost to replace the components and manpower for the job assume G3 qualified?

Best

Do the iso valves work .
