Why tankless is a focus

Tankless water heaters provide continuous hot water, take less space, and often last longer than traditional tanks when installed correctly. The difference is in the details: correct BTU sizing for the home, proper gas line capacity, correct venting, and code-compliant mounting and connections.

Diamond Quality Plumbing installs and services tankless systems for residential properties throughout the San Fernando Valley, including North Hollywood, Studio City, Sherman Oaks, Encino, Tarzana, Woodland Hills, and surrounding communities.

Common questions

How long does a tankless water heater last?

With proper installation and periodic maintenance, many tankless units last 15–20 years or longer — often longer than traditional tank heaters.

Do you only install tankless, or tanks as well?

Both. Tankless is a strong focus, but we also install and replace standard tank water heaters when that is the better fit for the home.
