Is this just bad luck or are Skoda fabia MK2 water pumps just W@nx. I changed the original when I rebuild engine for Mickey Mouse OEM an it lasted about 2 months. So I bought a Genuine one on the 01/06/2020 and it lasted about two weeks. I contacted the dealer where I bought it from an they said I had to book it in for a replacement, they fitted it.  This POS has just failed in the same way. The pumps seem to be leaking round the pulley bearing housing. They are absolutely ****e. Can anyone recommend anything like a upgraded part or something.  Its an absolute joke.

It sounds to me like the drive belt is much too tight causing gland and bush failure.

Ah you seem to run into the Fabia hocus pocus on pumps, my good friend was on a third pump that was also leaking  we finally sorted it out by making sure that the correct pump with the correct impeller was fitted as this makes a difference with different models, also you need to re fill system with the correct VW anti-freeze around £50 a shot, and you need to replace the tensioner pully at the same time, did this on his MK2 1.9 TDI and so far the pump has lasted 2 years and no leaks, belt and tensioner and pump were purchased from Skoda Parts. they are based in Europe so not sure now if you can get a decent price due too customs etc

OK, thanks for the tension idea, I have had another thought that would seem to in my opinion contribute. The coolant? The stuff from VW £50 a shot stuff. Is this like pure glycol? Assuming that this has a higher boiling point, about 190c apposed to crap from Halfords premix having water in it around 100c This would create pressure an pop the seal. My intention is to replace pump and tensioner and put vw coolant in. How much would I need in litres to fill the system?

I know what you mean but you're barking up the wrong tree, pure glycol is a very bad heat transfer medium and is always mixed with water in coolant, there is an OAT based waterless coolant used by the classic car community so that the system can be run without pressure to preserve elderly pipework, perhaps this is what you mean, however there's no need for it on a modern car with a high pressure cooling system.
