As part of the Commercial Plumbing Inspection we identify the type of plumbing installed in building, whether it is copper, galvanized, lead, PVC or pr
Your inspector will perform a visual observation and general operation of the plumbing system. The inspector will consider readily accessible pipes, fixtures and components, while noting recognized adverse and material defects present at the time of inspection. Minor defects may be also reported. The inspection typically reviews the visible water supply and waste removal sewage system. Water flow performance is judged by running water through the pipes and sewage systems in normal modes and in a representative manner. The water heater is usually inspected for heating performance and safe operation which may include venting and the temperature and pressure relief valve. Water heater types include reservoir and on-demand systems will be inspected and data recorded. Water heater ABS vents are being replaced with 636 rated PVC vents. If existing vent is covered with drywall etc. replacement could be very costly depending on location.
Your buildings plumbing system will include as a minimum the following items:
visual investigation and operation of all above ground, exposed plumbing, including shut-off valves and traps under kitchen, bathroom and laundry room sinks;
inspection of the hot water tank or tankless unit ( check for presence and correct location of PRV;
shut-off valve inspection and identify location;
inspection of bathroom, kitchen and laundry room installations to ensure draining and venting systems are not compromised;
basement floor drain system inspection;
sump pump and discharge inspection
Common Plumbing Defects Found During Commercial Inspections
Leaking pipes or condensation on plumbing lines = mold and structural damage.
Moving toilets = flange gaskets that lose their seal, leaks and quickly compromise the integrity of the subfloor and floor joists.
Inaccessible or inoperable main shut-off valve = inability to isolate water supply during an emergency.
Improperly installed drain and venting systems during kitchen and bathroom renovations = poor drainage and potential back-up.
Inaccessible or missing floor drains in the basement = inability for water to drain in case of spill, leak or hot water tank failure. Floor drain can also be utilized as an access point to investigate main sanitary drain system.
