NaOH reacts with Al to evolve H2 gas. Thus the pressure of the gas produced can be used for clogged drains. 2Al(s) + 2NaOH(aq) + 2H2O(l) ——-> 2NaAlO2(aq) + 3H2(g)
A mixture of dilute NaOH and aluminium pieces is used to open drain. Aluminium pieces dissolve in dilute NaOH to evolve dihydrogen gas whose presence can be used to open clogged drain.
