Water top up.

[The Tank]

For the last 4 weeks I have been topping up my water with at least 2 pints every week, I average about 500 miles a week and am sometimes caught in traffic for lengthy spells, so I am not sure if this ammount of water top up per week is normal. I cannot find any leaks anywhere either. Any help if poss. Thanks in advance.

Absolutely abnormal. If you can not find any leaks, the radiator cap can be faulty and lets the water out when under pressure. You may have a blown head gasket, and the water seeping into the oil. If so, you will find thick white goo in the oil filler cap. Yet another possibility: Do you see a leak from the water pump with the engine running?
Hope this helps ...

That's a lot of water. And since it seems to have come on in the last four weeks, it's not normal. I'd reckon you either have a leak somewhere or a head gasket problem. Check you passenger footwell carpets in case it's the heater matrix. Open the bonnet and look for steam with the engine running. What model is it?

You definitely have a problem, I have never had to top up my 1999 406 between services.

I had this problem on my 1998 diesel, it was the water pump leaking
