Tankless Water Heaters in Issaquah: what's different here
Olde Town's older valley homes and the foothill lots on Squak Mountain and Talus have very different water pressure and drainage needs. In Issaquah, tankless water heaters are a common upgrade when the original tank fails. We check gas supply and venting, and install a recirculation option where the bathrooms are far from the heater.
Permits and inspections
Switching to tankless needs a plumbing permit, and new gas lines or venting are part of the inspection. Mechanical and plumbing permits in Issaquah go through the City of Issaquah Permit Center. When the work needs a permit, we pull it, schedule the inspection and leave you the paperwork.
Utilities
Most Issaquah homes are on city water and sewer, so the main shutoff and sewer cleanout are usually easy to find.
