    Signs:
    Slow sink, tub or shower; standing water; recurring clogs
    Urgent when:

    The tank itself is leaking
    Before help arrives:
    Turn off gas or power and close the cold-water valve
    Repair or replace:
    Leaking tank: replace. Failed part on a younger tank: repair

Why Hilo homes need these repairs

Hilo is the county seat of the Big Island and one of the wettest cities in the country, with older plantation-era wood homes near the bayfront and newer subdivisions climbing toward Kaumana and Waiakea Uka. The county pumps its water from wells on the slopes of Mauna Kea and Mauna Loa. Heavy rain, humid salt air, termite-damaged wood framing, and catchment or well systems outside the county network drive most of the drain, water heater and pipe corrosion calls here.

Hilo's water supply and your plumbing

The Hilo water system is fed by groundwater wells: Pana'ewa Wells 1–3, Pi'ihonua Wells A–C, Saddle Road Well A and the UH Hilo Well. [1]

The Department of Water Supply notes that the sources used for Hilo may change depending on supply and demand. [2]

The Hilo system's sources are all wells rather than surface water. [3]

Hilo plumbing questions

Who should I call for a drain that keeps clogging in Hilo?

A plumber can clear the clog and, if it keeps coming back, inspect the line to find whether grease, roots or a damaged pipe is the cause. Why it comes up in Hilo: Heavy rain and roots overload older drain lines.

When is a leaking water heater an emergency in Hilo?

A leak from the tank itself won't stop and usually means replacement; turn off the gas or power and the cold-water valve, then call. Why it comes up in Hilo: Salt air corrodes tanks and solar water heater parts.

Where does Hilo's county water come from?

From county wells in Pana'ewa, Pi'ihonua, Saddle Road and at UH Hilo; it's all groundwater.

My Hilo-area home uses rain catchment. Can a plumber help?

Yes with pumps, filters and indoor plumbing; catchment water isn't treated by the county, so many owners add UV or filtration.

Does Hilo's salt air affect plumbing?

Yes. It corrodes metal fittings, outdoor hose bibs and water heater jackets faster, especially near the bayfront.

Do Hilo homes use solar water heaters?

Many do; panels, pumps and valves need periodic service, and a backup element covers rainy stretches.
