Leaking Valves

[Adam78]

It is possible that both your shower and radiators are weeping as a result of the change in pressure that they now have to withstand.
But be aware that the shower and its plumbing is now subject to mains water pressure. Whatever that maybe in your area (it can vary from day to day and minute to minute) the radiators should be subject to a minimum constant pressure of about 1-1.2 bar increasing when the system water in your radiators is hot but should not approach 3 bar.
I may be stating the obvious but your radiator loop and heating pipe work are entirely independant of the plumbing and water to your shower and taps.

Whats the recommended fix though if they are indeed weeping as a result of change in pressure?

did he change the shower/ has it been changed in the last 5 years? if no then new shower sorry to say as it wont be rated for med-high pressure

The weeping joints should be remade as they should be more than capable of withstanding the pressures of either the mains water system or your sealed Heating system. If you have excessive mains water pressure ( unlikely, but I don't know) you can have a pressure reducing valve fitted that would limit the property side pipe work pressure to 3 bar Max.
You could try just tightening the bust on the compression or union fittings that are weeping but sometimes this can make the weep worse not better and only experience will know which way they are likely to go.

No he didn't change the shower. What about a fix for radiator valves as they are new?

they just need inspecting and remaking like solutions said

Good point.
