A meaningful slice of our work is second visits: installs that someone attempted before calling us. The same five mistakes account for nearly all of them, and every one is avoidable.
Mistake 1: The Extension Cord Solution
No outlet behind the toilet, so a cord snakes across the floor to the vanity. It violates the manufacturer's requirements, voids warranty conversations, and puts a trip hazard next to porcelain and tile. The fix is a properly wired GFCI outlet, which is why one is included in every package we sell.
Mistake 2: Reusing A Tired Flange
The flange anchors the toilet to the drain. Setting a new fixture on cracked or corroded hardware means rocking, leaks, and eventually a rotted subfloor you cannot see until it is expensive. New flange hardware costs little at install time and a lot after tile comes up.
Mistake 3: Trusting An Ancient Shut-Off Valve
That crusty valve has one job on install day and one job in an emergency. Old valves seize open or weep at the stem the first time someone finally turns them. We replace it while the toilet is already out, the only time it is nearly free to do.
Mistake 4: Ignoring Rough-In Before Buying
The wall-to-bolts measurement decides what fits. Most Utah homes run the standard 12 inches, but enough do not that measuring before purchase is a two-minute insurance policy against a very heavy return.
Mistake 5: Skipping The Function Test
Wash, dry, heat, sensors, seal, and supply line all get verified before our techs leave. DIY installs usually test one flush and call it done, and the leak that reveals itself a week later does not send a warning first.
