~~ Solar Hot Water Heating Pre-Plumbing
Installation Requirements
i7n' OF
CHULA VISTA
Exhibit A
These requirements are applicable in all new Single Family Dwellings and Duplexes. They
also apply to Multi Family Dwellings where each unit extends vertically from the foundation
to the roof or where buildings have a central water heating system that serves all the units.
1. For roofs having less than a 4" in 12" slope that have clay or concrete roof tiles: Two
3/4" copper pipes and one 3!4" Electrical Metallic Tubing (EMT) conduit, shall be
stubbed out a minimum of 12" above the roof, capped off and provided with roof jacks
for a future solar hot water heating system. The pipe and conduit shall be run to the
location of the water heater, be capped off and be readily accessible.
2. For roofs having a 4" in 12" slope or greater with any type of roof covering: Provide
two 3/4" copper pipes and one 3/4" EMT conduit to an accessible location in the attic
a minimum of 6" above the insulation and be capped off. The pipes and conduit shall
be run to the location of the water heater, be capped off and be readily accessible.
3. Pipe and conduit should penetrate the roof in the lower one-third of the slope. This

members. (Per chapter 23 of the California Building Code in effect at the time of plan
check approval.)
12. Pre-plumbing/piping shall be complete for rough frame inspection.
