Microbore speed fit in concrete

[Mad Maximus]

Due to some enthusiastic diy’ing I nipped a rad pipe right at the floor so I had to chop a section of floor (concrete and screed) up to get to the leak and fix it.

I now have 2 microbore speed fit connections that are going to be under the floor (concrete). What’s the best way to protect them so they hopefully don’t cause problems in the future?

A decent stud detector that detects water and non-metal.

I always put delicate or hard to reach pipes inside a larger pipe or shroud them in that Hessian stuff if they're in concrete.

Do the same where pipes go through brick or similar too (eg pop a bit of 22 over a 15), as expansion and contraction can cause them to rub through.

Are you saying that the new joint would be encased in the concrete? Or below it? Neither is good but encased is bad..
Try to find a way to avoid this even if it means renewing a full section of pipe rather than a patch.

Wrap with foil gas tape.

Or, you could do what the plumbers I know did when their newly fitted 15mm rad pipes started leaking under a newly laid concrete conservatory floor. Push the microbore through the 15 mm pipe and use the 15 as shielding.

When the heating was put in with the previous owners the pipe was laid into the floor encased in concrete so now I’m going to have the same but this section will have two connections on it where I’ve had to repair.

Ideally I would run a new section but that would be so horribly horrid to do it’s not going to happen.
