There have been numerous leaks in the copper domestic hot and cold water piping, resulting in property damage.
The soldered joints in the copper water piping were over fluxed. This has caused flux corrosion and leaks.
The copper water piping was not reamed at the tubing ends. This can cause internal erosion of the tubing and fittings.
The water heaters have no drain pan, as per manufacturer's installation instructions. This will likely cause water damage to property in garage.
The shut-off valves for the water supply are corroded and leaked and caused damage. The valves were not properly selected by the contractor for this service and are dezincing.
Certain high-efficiency water heater PVC flue vents are not insulated, as per manufacturer's installation instructions.
There is no insulation on the hydronic hot water supply and return piping that provides hot water heating to certain fan coils. California Title 24 requires this piping to be insulated.
Certain laundry washing machine indirect drains are not readily accessible and the water valves are not accessible. They are located behind the stacked washer/dryer.
Certain 3" PVC water heater flue vent penetrations are not properly fire rated through the all in violation of the building code. This occurs through certain units and in the electrical rooms.
Hot water takes over a minute to warm up in the bathrooms. One minute was used at the criteria even though most reasonable homeowners expect hot water in less than 30 seconds.
The unit sub panel enclosure is setback and has gaps in the drywall greater than the code allowance.
The A/C unit disconnects have inadequate working clearance.
The cables are insufficiently supported as required by code.
The cables within 6 feet of the attic access are not protected from damage.
The recessed lights fixture sockets have been over sprayed with paint/or drywall texture.
The electrical device boxes are setback and have gaps in the drywall greater than code allowances.
The boxes installed in rated walls are improperly installed.
The conduits and/or cables are insufficiently supported as required by code in the electrical closets.
The exterior exposed light fixtures are not sealed to prevent water intrusion.
Quality of Workmanship.
Certain flexible A/C ducts are not supported or installed properly, and are kinked.
The A/C condensate drain piping was not installed properly. Based upon the installation instructions, it does not contain proper traps, and is not vented or supported properly. This has caused premature flow to secondary drains causing damage.
The condensing units are not identified with the unit address as is required by the mechanical code.
Clearance around the outdoor condensing units is not adequate and does not comply with the manufactures requirements.
The condensing units are not level as required by the unit manufacturer.
The refrigeration tubing insulation at the outdoor condensing units was not rated for exterior application and is deteriorating from exposure to ultra violet light.
The refrigeration tubing penetrations of the exterior walls are not sealed as required by building code and energy code.
The flexible dryer vents are kinked in the laundry closets. This causes poor dryer performances and creates a fire hazard.
There are no check valves on the hot water recirculation fan coil heating loop. The check valves should be located at the recirculation pump discharge.
The laundry closets were not provided with an exhaust fan. This is a code violation.
