Professional Toilet Repair & Installation for Oʻahu properties
A running toilet wastes water, while leaks at the base or repeated clogs can damage surrounding finishes and interrupt daily use. Waialae Plumbing repairs common toilet problems and installs replacement fixtures for homes and commercial properties.
Call when a toilet will not stop running, water appears around the base, the fixture rocks, or clogging becomes a pattern rather than a one-time event.
Replacing a toilet? Check the BWS rebate first.
Eligible Honolulu Board of Water Supply customers may receive up to $200 per toilet when replacing an older toilet with a qualifying WaterSense-labeled model using 1.28 gallons per flush or less. Limit four toilets; new construction excluded. Applications must be submitted within six months of purchase. Additional eligibility requirements and funding limits apply. Call or text (808) 735-8595 for details, or text our office.
This is a BWS rebate, not a Waialae discount or guaranteed payment. The rebate cannot exceed the pre-tax product cost.
Which replacements qualify?
The new toilet must be EPA WaterSense-labeled and use 1.28 gallons per flush or less, replacing an existing toilet using at least 1.6 GPF. Tank and bowl must be purchased together. New-construction homes are excluded; prior rebates can affect eligibility.
What paperwork is needed?
Keep an itemized receipt identifying the model, quantity, unit cost and purchase date. The toilet must be installed, and BWS must receive the application within six months of purchase. Funding and approval are subject to program terms.
Check current BWS eligibility and application instructions. Program information checked October 21, 2026.

Toilet Repair & Installation FAQs
Can you install a water-efficient toilet?
Yes. Waialae Plumbing can install an appropriate replacement fixture selected for the space and customer’s preferences.
Why is my toilet running by itself?
Worn tank components or a poor seal often allow water to escape and trigger refilling, but the fixture should be inspected to confirm the cause.
Does a clog always mean the toilet is the problem?
No. Repeated or multi-fixture backups may indicate a branch or main drain issue rather than a defect in the toilet itself.
