Plumbing & Piping
Plumbing & Piping Site Survey
Field checklist for existing-condition and construction observation of domestic water, drainage, fuel gas, and fixtures. Record tags, sizes, and deficiencies while access is open.
Domestic Water Heating
- Record water heater or boiler manufacturer, model, serial, input, recovery, storage volume, and fuel.
- Note setpoint, aquastat, mixing valve, and outlet temperature where the plant allows a reading.
- Verify T&P relief discharge termination, drain pan, and thermal expansion tank.
- Log recirculation pump tag, balancing valve, and insulation on the hot water and return.
Service Entrance & Backflow Prevention
- Record service size, meter, and pressure-reducing valve setting if labeled.
- Identify backflow assembly type, size, serial number, and the date on the test tag.
- Confirm relief-valve discharge has a visible air gap and a drain that can take the flow.
- Note isolation valves, strainer condition, and any assembly installed below grade or without clearance.
Sanitary & Storm Drainage
- Count fixtures by area and compare the count to the drainage load the piping appears to serve.
- Locate floor drains, trench drains, trap primers, and cleanouts. Note covers that are buried or sealed.
- Record grease interceptor location, capacity if tagged, and inlet and outlet condition.
- Photograph roof drains, overflow drains, and scuppers. Note ponding and missing domes.
Fuel Gas
- Record meter size, delivery pressure, and regulator location.
- Note piping material, support spacing, and bonding jumpers at meters and appliances.
- Verify appliance shutoff valves, dirt legs, and connector condition.
- Check combustion-air openings and vent connectors. Do not assume a sealed opening is code-compliant.
Fixtures by Occupancy
- Food service: count prep sinks, warewash, mop sinks, and floor drains at the cooking line.
- Healthcare: record clinical sinks, bedpan washers, and emergency fixtures separately from public toilets.
- Multi-family: note water closet type, shower valve, and whether units share a water heater or riser.
- Industrial: log hose bibbs, emergency eyewash and shower locations, and vacuum breakers on washdown stations.
