Plumbing in the Tri-Cities
A-One's plumbers work on water heaters, drains, leaks and fixtures for homes and businesses in Pasco, Kennewick, Richland and the towns around them.
PlumbingHomesBusinesses
Residential and commercial plumbing from one shop
A dripping faucet, a clogged drain, a running toilet or a leak you cannot see can turn into a real problem quickly. A-One's plumbers diagnose the cause first, explain what they found, and then repair it with parts that match the plumbing already in your walls.
The crew works on houses and on businesses, from a single fixture to a full repipe. Plumbing is a trade we run alongside heating, cooling and electrical, so one call to the Pasco shop can cover the whole building. We aim for prompt service, clear communication and workmanship you do not have to think about again.
Water heaters
Water heaters, tank and tankless

Tankless water heaters
On-demand hot water sized to your house. A-One plans the install, services existing units and descales heat exchangers clogged by hard Tri-Cities water.
Water heater repair
No hot water, a rumbling tank, rusty water or a puddle at the base. A-One tests the heater before replacing anything and tells you if it is worth repairing.
Water heater replacement
When the tank is done, A-One sizes the new heater to your household, sets it with new connectors and straps, and checks every joint before we leave.
DrainsLeaksFixtures
Drains, leaks and fixtures
Drain clearing
Slow sinks, backed-up tubs and floor drains that will not clear. A-One's plumbers find where the clog sits, clear it with the right tool and tell you why it formed.
Emergency plumbing
A burst pipe, a backed-up drain or a water heater dumping onto the floor. A-One offers 24/7 emergency plumbing for homes and businesses across the Tri-Cities.
Faucets and fixtures
Dripping faucets, running toilets and stiff valves. A-One repairs the worn part where that is enough and replaces the fixture where it is not.
Leak detection
A water bill that climbs, a warm patch on the floor or a meter that keeps turning. A-One locates the leak before anyone opens a wall, then repairs it.
Plumbing repair
Leaking pipes, failed connectors, stubborn clogs and water heater trouble. A-One's plumbers find the cause, explain the options and repair it.

Other plumbing jobs the crew takes on

Ask for these when you call. If a repair turns into a bigger job, the plumber will tell you before the work grows.
Emergency24/7
When a pipe lets go, do these two things first
A-One offers 24/7 emergency service, and the minutes before a plumber arrives matter.
- Find your main shutoff and turn it clockwise until it stops. In most homes it is in the garage, at a crawlspace wall or near the water heater.
- Turn off the water heater, at the gas control or the breaker, so it does not fire or burn out while the tank drains.
- Then call us. Tell the office what you see and where the water is coming from.
