check out the plumbing

[ostap77]

Could I say "checking out the plumbing" for "using the bath room."?

I haven't met it in the UK, but it's possible. 'Plumbing' and 'waterworks' are a commonly used euphemism - in medical circles - for gastro-intestinal and urinary problems.

('Waterworks' has another metaphorical use in other contexts - 'crying': 'Whenever I mention my poker nights (Thursday, without fail) she turns on the waterworks.')

Yes.
"I've got to check out the plumbing" is a somewhat crude way of saying, "I need to go to the bathroom.'

Use this expression carefully; not in mixed company or in a professional setting.

I've often said and heard 'I'm going to inspect the plumbing' (check out is more of an AE expression, as is bathroom for toilet.

I consider it to be in no way crude and would use it in any company.

I agree with Rover and would not hesitate to use the expression in mixed company. I think 'I need to check out the plumbing' sounds better than saying 'I have to go to the bathroom.' ;-)
