Mains water- massive over pressure

Hello

So Wednesday night I was doing the washing up and ran he tap and it blasted out, never seen such pressure.

Turned tap off and could hear noise under the sink. Looked down to see water pouring out from bottom of cabinet. Opened door to get to stop tap and was blasted full in the face by water from a split in a hose tap connector.

Finally got stop tap closed but by this time water everywhere- under all the cabinets and under the lino so large mopping up sussion ensued.

I contacted Scottish Water and the recording advised there were currently burstg water mains in my postcode area. Got through to someone to ask about high water pressure. He logged the call.

20 mins later he phoned back to confirm engineers were working in my village and had accidentally over pressurised the system - something about installing a back feed.

I think we have cleaned up ok but concerned about the water getting under the lino. Scottish Water advised they do have a claim scheme.

Now, the reason for my cool story is that our friends up the road noticed on Thursday morning that their bathroom floor laminate(in a bungalow) was very squelchy but they could see no evidence of a leak. Today we took the bath panel off and there is a lot of water under the bath but no evidence of water escaping now. However, there id evidence of quite a torrent of water coming down the wall, most likely from the shower (behind the tiles)

It is a Triton Amber III. I see it has an overpressure relief valve which doesn't seem to have activated. There is no water leaking now. Is there anything in an electric shower that could give way and leak under pressure and then seal again at normal mains pressure.

It is too coincidental that there floor was saturated at the time of the overpressure on the mains, but the leak has disappeared now

What could cause it?

Srry for the ramble
