Access to underfloor pipes when replacing a boiler
I'm looking to replace my bathroom. Before I tile the floor, I'm curious to know if access if to the pipes underneath the floor boards would be needed if I choose to replace my old boiler in the near future.
In my experience it is always prudent to replace pipework that is under a bathroom floor I always try to have no joints on the pipework aswell as the last thing you want to have to do is have to lift tiles then decoupling membranes and plywood etc
If you are replacing a combination boiler for another combination boiler you should not need access to the pipes under the floor boards, however if you are replacing all the pipes as well as the boiler then you will.
