Floor Repair - Best Approach?

[Gizzydash]

Hi all,
Have to repair floor on pic attached, old solid floor. What's best approach to this, mix up some mortar and patch it in? Worried about mortar around copper pipes, or do I compact loose stone around them and mortar on top?
Any advice appreciated!
Thanks

I've seen them wrapped in waterproof tape, but the brass connection joint you have is a source of possible leaking.

Pack soft sand around the pipes so that you have a flat surface just above the pipes then lay polythene on top - then concrete over.

Thanks noseall - sounds like a plan.
Wasn't expecting the sand but makes sense - sharp sand?
Lap the polythene up sides a bit and concrete to level, planning to slc whole floor once I patch this bit.

sharp sand?

Pack soft sand

Builders sand/bricklaying sand.

Sorry to round back on this but just about to buy materials. Definitely concrete i'm using and not a mortar mix - so cement, sand and stone aggregate mix? Lot of the pre-mixed stuff for floor repair looks like just a mortar mix so will have to mix up some concrete myself if needed
Thanks

You can use screed sand (AKA sharp sand/concrete sand) as it will bind in to the existing better.
