Water heater service in Rancho Santa Margarita: what to know

Rancho Santa Margarita sits east of Mission Viejo in ZIP 92688. The city was built mostly in the late 1980s and 1990s, so many homes are now on their second or third water heater. Tank replacements, leaks and tankless upgrades are the most common calls here.

The city centers on RSM Lake and Central Park, with neighborhoods along Santa Margarita Parkway, Antonio Parkway and Avenida Empresa. Tijeras Creek Golf Club and the foothills of the Santa Ana Mountains frame the east side.

Water comes from the Santa Margarita Water District, which is based in Rancho Santa Margarita. The water is moderately hard, so tanks collect sediment and tankless units collect scale. Many condos and townhomes here have water heaters in closets or tight garages.

What water heater problems are common in Rancho Santa Margarita homes?

Rancho Santa Margarita homeowners most often call about tanks leaking at the bottom, replacements of 1990s-era setups, sediment noise and tankless descaling. Older installs also often need seismic strap and expansion tank upgrades when the unit is replaced.
