Process

Tankless installation

The home and peak demand come before the product.

STEP 01

Measure demand

Simultaneous fixtures and required temperature rise set the flow target.

STEP 02

Check the home

We review gas, power, venting, combustion air, condensate, piping, and mounting space.

STEP 03

Install and commission

We test temperature and flow, then show you the shutoffs and flushing access.

Diagnosis

Does tankless fit?

Tankless works only when the building and usage pattern support it.

Peak flow

Sizing follows the fixtures that may run together, not average daily use.

Required upgrades

Gas, venting, condensate, or electrical work can change the project cost.

Future service

Isolation valves and clear access make flushing and repair practical.

Vancouver & Clark County

Cold-weather sizing

Cold winter inlet water requires more temperature rise. Vancouver-area sizing should use realistic cold-weather demand.

True Plumbing is an excellent and fair business. Jason R. Is very skilled and personable. I appreciate his professionalism and confidence. He wants to do things perfectly correct. I recommend Jason, Danny and True Plumbing.

Joseph SligerTrue Plumbing

Everything about working with True Plumbing was top notch, professional, and still human and friendly. Nick came out to consult, and he was both knowledgeable and friendly. Eric showed up on time and ready to rock. He encountered and overcame some unforeseen challenges (behind our walls) without missing a beat. I was wrongly skeptical of a one man show taking on the task, but he got it done and within the time they had quoted. Add to all this, they did it for 20% less than my previous bids. I will definitely be recommending True Plumbing to others.

Good to know

Tankless questions

Is a tankless water heater worth it for a Vancouver home?
It can be when you value compact equipment and long hot-water runs, and the home supports the flow, utilities, venting, condensate, and service access.
How do you size a tankless water heater?
Add the flow of fixtures that may run together, then apply the temperature rise from incoming water to the desired outlet temperature.
Will my gas line support a tankless water heater?
Check the meter or regulator, total appliance load, pipe size, route length, and pressure before deciding.
What other upgrades can a tankless installation require?
Gas piping, venting, combustion air, condensate drainage, electrical service, water connections, isolation valves, or mounting.
Does tankless mean hot water reaches the faucet instantly?
No. Water in the branch pipe still has to clear. Pipe length and recirculation determine the wait.
What maintenance does a tankless water heater need?
Follow the model’s schedule for scale control, inlet-screen cleaning, safety checks, and clear service access.
Thinking tankless?

Price tankless.
