SCOPE OF WORK:
This roof drain installation project was done by All Tech Plumbing, the parent company to Roof Drain Pans Co.
This project is located in Hawthorne, CA. This was a two story concrete tilt up building with a wood framed roof. .
There were five existing roof drains that were sitting too high on the roof and were undersized which caused pools of standing rainwater and subsequent roof damage. Also there were three separate ponding areas that had no roof drains. All of the overflow roof drain were grossly undersized.
To correct the problems, All Tech Plumbing installed all new 15″ primary and overflow roof drains and sumped them using model LSP roof drain sump pans.
Wall coring was required for the roof drain piping to pass through the concrete wall in order to convey the rainwater to the exterior of the building.
Materials used:
- LSP roof drain sump pans, Zurn 15″, Z100 primary roof drain and ZC100-89 overflow roof drain.
- Cast iron piping and fittings. No hub couplings.
