Dropping coolant following new pipes?

Hello,



Scuse my possible ignorance - I had new SS coolant pipes fitted to my TF on Sunday by a highly recommended mobile mechanic.



Following this, I've had to top up my coolant twice (Sunday evening and today lunchtime). Nearly 2 litres. Is this just the coolant being taken up by the system or something, or do I need to be ringing the mechanic? Read some stuff about incorrect bleeding but tbh I can't tell fact from fiction currently!



Can't see any damp patches under the car but where I park is a sopping muddy patch and its difficult to really see anything other than leaves... Have also been under the car with a torch in the dark as well as in natural light and can't see drips/leaks/etc.



Thanks!
