You clearly are a bodger by what you describe. Tsk, tsk.

If the fittings are placed tightly to the joists then there may be
insufficient provision for expansion and contraction and therefore a
potential straining of the joints. Undulation in the pipe may provide
enough expansion capability but care does need to be taken to ensure
that there is provision for thermal effects.

No need to bother with expansion space if you've made the joints with a
hacksaw - they'll leak anyway...
