Unpermitted Basement Bathroom and Sump Pump Discovered During Water Heater Replacement
A journeyman plumber is called to replace a leaking 40-gallon electric water heater in a finished basement. While moving the old heater, the plumber sees a recently added bathroom: toilet, lavatory, and shower draining into a 2-inch PVC line that runs to a sump pit with a submersible pump. The pump discharges through a garden hose to the floor drain. There is no vent on the bathroom fixtures, and the shower drain has a 1-1/2-inch trap with a 10-ft trap arm to the sump. The homeowner says a handyman installed it last year and insists no permit is needed because it is in the basement. The water heater replacement also lacks a permit, and the heater is in a closet with no drain pan. The local code requires permits for water heater replacement and new plumbing, and the sump is not a listed sewage ejector.
1. Identify the code and licensing problems and state what the plumber should do before replacing the water heater.

The bathroom is unpermitted and likely unsafe: no vent, an unlisted sump used as a sewage ejector, and a garden-hose discharge. The water heater replacement also requires a permit, and a drain pan is needed where leakage can cause damage. The plumber should not conceal or ignore the illegal work. Stop, document with photos, inform the owner in writing, and require permits and inspections. A handyman exemption does not make unvented DWV or an unlisted pump legal. If the owner refuses, the plumber should decline the illegal scope or limit work to the permitted water heater and report as required. Verify Ohio and local rules.
2. Explain why the sump, hose, and lack of vent are unacceptable and what failures they can cause.

A sump pit with a submersible pump is not a listed sewage ejector basin. It may not be sealed, vented, or sized for solids, and the pump may not handle sewage. A garden hose is not an approved discharge material, can collapse or kink, and lacks a check valve and full-size discharge. Without a vent, the bathroom traps are not protected; discharging fixtures siphon traps, and the pit can release sewer gas. The 10-ft 1-1/2-inch trap arm also exceeds normal limits. Risks include sewer gas, backups, pump failure, and contamination.
3. Outline the corrective work and inspection sequence.

Obtain permits. Remove the illegal bathroom drain or rebuild it with proper DWV, vents to the existing stack or roof, and a listed sewage ejector basin with a sealed cover, vent, 2-inch discharge, check valve, and alarm. Install a water heater drain pan with T&P discharge to an approved location. Pressure-test or water-test the DWV, inspect before covering, test ejector operation, and obtain final inspection. Provide as-built information and maintenance instructions. Do not energize or commission the work until it is approved.
