    Trader put a nail into my underfloor heating

    You let a trades person drill into your floor that has underfloor heating? You are accusing the guy of being at fault? Next you will be claiming the underfloor heating installer encouraged you to have people round drilling holes in the floor. I'd be fuming as the joiner.

    150mm is 150mm though no? 125 between and 25 beneath can't really be much of a difference at all in u value unless I'm missing something else?

    Chasing basin waste and hot and cold pipe into wall

    The waste will be 32mm for the sink. I'd be chasing it in all day long. If it's getting dot and dabbed there will be a 10mm ish gap between wall and board also. Pipes effectively need chasing In a very minimal amount. You can't run them external on show and why bother with a boxing in?

    Will removing a TRV lead to water leaking?

    The head of the trv does un screw and water should not leak out. If the head is already loose and on its highest setting it is goosed! Ps- make sure valve on other side of rad is open to!

    Will removing a TRV lead to water leaking?

    The most likely cause is that the valve is stuck shut, replacing the head of the valve will make no difference at all. It needs a new valve really but removing the head and lifting the pin up a couple of mm may well get the rad working. You won't be able to use the head again though as when it...
