hypothetical plumbing disaster: bidet edition

I’d close the toilet’s shutoff valve first, if I could reach it safely. If it won’t stop the spray, then shut off the main; once the water’s under control, I’d check the connection and call a plumber if I couldn’t tell what had failed. Mopping can wait until the flow stops.

Once the spray is stopped, what would make you comfortable resuming - only a shutoff valve that fully stops the water and a connection that looks sound, or would any spray make you leave the rest to a plumber?

I wouldn’t treat every spray as an automatic plumber call, but I’d resume only if the shutoff fully stops the water and I can identify and correct the loose or misaligned connection. If the valve still leaks, a part looks damaged, or I can’t tell where the water escaped, I’d leave it off and call a plumber rather than guess.

If the shutoff fully stops the water and you’ve corrected an identifiable, undamaged connection, I’d reopen it slowly while watching that joint. If water starts escaping again, close it and don’t keep adjusting under pressure; leave it off and get help if the cause isn’t clear.

The mop-up can wait until the spray is stopped. After that, I’d check where the water reached and clean it up rather than letting embarrassment make me ignore it; if it got into flooring or a wall, I’d take that more seriously than a small puddle on a hard surface.

That visible-versus-hidden distinction matters: if water ran under or behind the toilet, wiping the exposed floor may not reach what’s trapped there. I’d check the nearby edges and dry what’s accessible; a damp seam or lingering moisture would be a reason to look further rather than assume the cleanup is done. That doesn’t mean damage has occurred, just that the hidden area shouldn’t be ignored.
