radiator pipes

[Mark B]

Even if you use the slot cutting method you could still drill the hole first as it would give a much neater finish around the pipe.

As mentioned, the problem with draining down the system is that you're never quite sure what's going to happen (or not!) when you fill it back up again - air locks, sludge blockages etc.

If you do drill holes stick with the 1x40mm from the BFKMX.

Heres why:

We performed a little test ourselves to MINIMISE the hole (and therefore the amount of tile we needed to remove) but found cutting two smaller holes at 30mm made very little difference.

Results:

To the left you can see we removed enough tile to slip the valve through. 2 x 30mm holes were cut so that the hole was an elliptical shape.

On the right you can see the amount of tile saved (shaded in black) when a 40mm crown was placed on top.

As you can tell from that shaded black area the decrease in hole size is so insignificant as to make that particular technique overcomplicated.

Our advice for boring a hole with the simple purpose of bringing through a standard radiator valve on a floor tile is to stick with size 40mm and cap-off with a 45mm cover plate.

The additional benefit is that if the cover plate is lost or broken later then at least the workmanship is neat and tidy with a single hole.

:lol:id cut around them like the one in gaz is pic doesnt look to bad for the sake of having to get in a heating engineer just for a couple of cuts seems pointless i doubt much of the customers around preston would pay for that alot of them are tight:lol:
