Private I Plumbing

Every Leak Tells a Story.

Professional Plumbing Services | Private I Plumbing

We investigate residential plumbing problems, find the cause, and make the repair. From water heaters and hidden leaks to water pressure, repiping, drains, and the lines serving your home, we follow the evidence from the first clue to the final solution.

Seattle & the Pacific Northwest

The agency

Plumbing leaves clues.

Private I Plumbing is a residential plumbing company built on a detective idea: every problem has a cause, and the cause is what we find first.

File · Agency

We are not trying to look like every other plumbing contractor. The private-investigator theme is the brand — sophisticated, black and gold, Pacific Northwest — not a costume.

A leak leaves evidence. A failed water heater has a cause. Low pressure has clues. We investigate the problem, name the diagnosis, and solve the case.

Based in Seattle & the Pacific Northwest, we take residential calls seriously and leave the work documented.

The path

How a case works

Evidence, then the cause, then the repair. The same order on every call.

  1. Evidence

    Water where it should not be. Corrosion on a fitting. A sudden change in pressure. A water heater that stops keeping up. Every sign can tell us something about what is happening inside your plumbing system.

  2. Investigation

    We trace the signs back through the system to find where the problem started. The visible symptom is only part of the case. The cause is what matters.

  3. Diagnosis

    Once the evidence points to the source, we identify the problem and explain what is happening. No guessing. No treating the symptom without understanding the cause.

  4. Solution

    With the cause identified, the appropriate repair or replacement is completed correctly. The goal is simple: solve the problem and leave the plumbing in proper working order.

The difference

Why open a case with us

Don't guess. Investigate. The repair comes after the cause is clear.

  • 01

    Diagnosis before repair

    We name the problem before the wrench turns. The house tells a story; we read it first.

  • 02

    Real cause, not guesswork

    Symptoms are clues. We follow the evidence to the pipe, valve, heater, or line that failed.

  • 03

    Documented work

    Scope, findings, and the fix — left clear so you know what was found and what was done.

  • 04

    Local residential focus

    Seattle and the Pacific Northwest homes we know. Residential plumbing, handled like a case file.

Residential plumbing

What we investigate and repair

Every call starts with a problem. Our work is to follow the clues, identify the cause, and complete the repair.

Water heaters
01

Water heaters

Leaking tanks, failing components, aging units, and heaters that no longer deliver the hot water your home needs.

Hidden leaks
02

Hidden leaks

Water can travel away from its source before it becomes visible. We investigate the signs and trace the leak back to where the case began.

Water service
03

Water service

The line connecting the meter to your home can fail, leak, or restrict flow. We investigate the service line when the evidence points beyond the fixtures.

Water pressure
04

Water pressure

High or low water pressure is a clue, not always the cause. We trace the pressure problem back to its source.

The Case of the Disappearing Water Pressure

Repiping
05

Repiping

Sometimes the problem is not one fixture or one connection. When the piping itself has become the issue, we investigate the condition of the system and determine the appropriate path forward.

Valves
06

Valves

A valve that leaks, sticks, or fails to shut off can create a larger plumbing problem. We identify the failure and address the source.

Drains
07

Drains

Slow drains and recurring backups leave clues. We investigate what is affecting the drainage system rather than simply treating the symptom.

Tankless systems
08

Tankless systems

Scale, fault codes, poor performance, and systems that stop delivering reliable hot water can all point to an underlying issue.

Gas piping
09

Gas piping

New gas lines, corrections, and related plumbing work completed according to the requirements of the job.

Code corrections
10

Code corrections

When existing plumbing does not meet current requirements, we identify what needs to be corrected and bring the affected work up to code.

Unusual problems
11

Unusual problems

Not every plumbing problem follows a familiar pattern. When the symptoms do not match a standard failure, we investigate the case from the evidence up.

Water heater repair & replacement
12

Water heater repair & replacement

When a tank leaks, fails to heat, or ages past reliable service, we diagnose the unit and repair or replace it correctly.

Gas water heaters
13

Gas water heaters

Gas-fired tanks that will not light, vent correctly, or deliver steady hot water need a focused investigation of combustion and plumbing.

Electric water heaters
14

Electric water heaters

Element failures, thermostat issues, and tank leaks leave clear clues. We trace the failure and restore electric hot water service.

Heat-pump / hybrid water heaters
15

Heat-pump / hybrid water heaters

Hybrid units that underperform, fault, or freeze up need diagnosis of both the plumbing connections and the heat-pump system.

Water heater maintenance & flushing
16

Water heater maintenance & flushing

Sediment, scale, and neglected anodes shorten tank life. Scheduled flushing and maintenance keep the unit working longer.

Hot-water recirculation systems
17

Hot-water recirculation systems

Long waits for hot water point to recirculation pumps, timers, sensors, or loop design that need investigation.

Thermostatic / tempering valves
18

Thermostatic / tempering valves

Mixing valves that fail to temper water correctly create scald risk or lukewarm delivery. We identify and correct the failure.

Expansion tanks
19

Expansion tanks

Water hammer, relief-valve discharge, and pressure spikes often point to a failed or missing thermal expansion tank.

Whole-house repiping
20

Whole-house repiping

When leaks and failures keep appearing throughout the home, the piping system itself becomes the case — not one fixture at a time.

PEX-A repiping
21

PEX-A repiping

PEX-A repiping replaces failing distribution lines with flexible, durable piping suited to modern residential systems.

Copper pipe repair & replacement
22

Copper pipe repair & replacement

Pinholes, green corrosion, and failed solder joints call for targeted copper repair or section replacement.

Galvanized pipe replacement
23

Galvanized pipe replacement

Galvanized steel restricts flow and corrodes from the inside. When the evidence points to galvanized, replacement is often the lasting fix.

Water service repair
24

Water service repair

Leaks or damage on the line between the meter and the home can often be repaired when the failure is localized and the pipe is otherwise sound.

Water service replacement
25

Water service replacement

When the service line is too far gone for a reliable repair, full replacement restores pressure and stops ongoing loss.

Main water shutoff replacement
26

Main water shutoff replacement

A main shutoff that leaks, seizes, or will not close fully is a critical failure — we replace it so you can control the system.

Pressure-reducing valves (PRVs)
27

Pressure-reducing valves (PRVs)

High municipal pressure or a failed PRV can damage fixtures and appliances. We diagnose and correct pressure regulation.

Water-pressure diagnosis & repair
28

Water-pressure diagnosis & repair

High or low pressure is a clue. We measure, isolate, and repair the cause — regulator, restriction, or supply condition.

The Case of the Disappearing Water Pressure

Leak detection & plumbing diagnostics
29

Leak detection & plumbing diagnostics

When water loss or damage has no obvious source, we investigate systematically until the leak or failure is identified.

Water-line leak repair
30

Water-line leak repair

Supply-line leaks behind walls, under slabs, or in crawl spaces are traced and repaired at the failed section.

Emergency plumbing repairs
31

Emergency plumbing repairs

Active leaks, burst lines, and sudden failures need fast isolation and repair. We open the urgent case and stop the damage.

Toilet installation & replacement
32

Toilet installation & replacement

Leaking bases, cracked bowls, and outdated toilets are replaced and set correctly so the fixture seals and flushes reliably.

Toilet repair
33

Toilet repair

Running toilets, weak flushes, and fill-valve failures are diagnosed and repaired without replacing the whole fixture when the evidence allows.

Bidet installation
34

Bidet installation

Bidet seats and attachments need correct water supply, isolation, and mounting. We install them cleanly and to code expectations.

Faucet installation & replacement
35

Faucet installation & replacement

Dripping, seized, or outdated faucets are replaced with correct deck fittings, supply lines, and shutoffs.

Kitchen plumbing
36

Kitchen plumbing

Sinks, supply lines, disposals, dishwashers, and related kitchen connections investigated and repaired as one system.

Bathroom plumbing
37

Bathroom plumbing

Toilets, lavatories, showers, and tubs share supply and drain systems. We diagnose bathroom failures and close the case correctly.

Shower valve installation & replacement
38

Shower valve installation & replacement

Failed shower valves cause leaks, scald risk, and no control. We replace cartridges or full valves behind the wall when needed.

Tub / shower plumbing
39

Tub / shower plumbing

Tub and shower supply, drains, overflows, and valves form one case file when leaks or performance problems appear.

Laundry plumbing
40

Laundry plumbing

Washer boxes, standpipes, and laundry supply lines fail in ways that flood quickly. We investigate and correct laundry plumbing.

Laundry boxes & drain pans
41

Laundry boxes & drain pans

Outdated laundry boxes and missing drain pans leave washers unprotected. We install or replace them for safer laundry setups.

Utility-sink installation
42

Utility-sink installation

Utility sinks need proper supply, trap, and drain routing. We install them for garages, basements, and laundry rooms.

Dishwasher installation & plumbing
43

Dishwasher installation & plumbing

Dishwashers need correct supply, drain high-loop or air gap, and leak-free connections. We handle the plumbing side of the install.

Angle-stop replacement
45

Angle-stop replacement

Under-sink and toilet shutoffs that drip or seize are replaced so you can isolate fixtures without drama.

Fixture supply-line replacement
46

Fixture supply-line replacement

Aged braided or soft-copper supply lines fail without much warning. We replace them before or after they leak.

Drain repair & replacement
47

Drain repair & replacement

Failed traps, corroded drain arms, and broken waste lines are repaired or replaced so fixtures drain without leaks.

Drain cleaning
48

Drain cleaning

Slow drains and backups leave clues. We clear the line and investigate what keeps returning after a temporary fix.

Sewer / drain camera inspections
49

Sewer / drain camera inspections

When the cause is underground or inside the line, a camera inspection shows the evidence — offsets, roots, scale, or collapse.

Hydro jetting
50

Hydro jetting

Grease, scale, and heavy buildup often need high-pressure water jetting beyond a standard cable clear.

Waste and vent piping
51

Waste and vent piping

Improper waste or vent piping causes slow drains, gurgling, and sewer odors. We correct the drainage and venting path.

Plumbing vent alterations
52

Plumbing vent alterations

Roof vent moves, island vents, and remodel-driven vent changes must be designed so the drainage system still breathes correctly.

Plumbing remodels
53

Plumbing remodels

Full plumbing remodels need rough-in planning, fixture coordination, and finishes that close cleanly. We handle the plumbing file end to end.

Kitchen remodel plumbing
54

Kitchen remodel plumbing

Island sinks, dishwasher moves, pot fillers, and new layouts need kitchen remodel plumbing planned before cabinets close.

Bathroom remodel plumbing
55

Bathroom remodel plumbing

Moved toilets, new showers, and double vanities require bathroom remodel plumbing that is laid out and finished correctly.

Natural-gas line installation & repair
56

Natural-gas line installation & repair

New gas runs and repairs to existing lines are sized, routed, and tested to meet the load and the jurisdiction’s requirements.

Gas appliance connections
57

Gas appliance connections

Water heaters, dryers, ranges, and other gas appliances need correct connectors, shutoffs, and leak-tested connections.

Cooktop / range gas connections
58

Cooktop / range gas connections

Cooktops and ranges need properly sized gas supply, shutoff access, and a clean connection inside the cabinet or behind the unit.

Hydronic heating plumbing
59

Hydronic heating plumbing

Boilers and hydronic loops depend on correct piping, pumps, and valves. We investigate and repair the plumbing side of hydronic heat.

Radiant-floor heating plumbing
60

Radiant-floor heating plumbing

Radiant manifolds, loops, and supply piping need careful diagnosis when floors stay cold or loops leak.

Boiler-related plumbing
61

Boiler-related plumbing

Near-boiler piping, feeds, relief valves, and closely related connections are investigated when the hydronic plant misbehaves.

Backflow / DCVA installation & replacement
62

Backflow / DCVA installation & replacement

Backflow preventers and DCVAs protect the potable supply. We install, replace, and support testing requirements for these devices.

Plumbing inspections & troubleshooting
63

Plumbing inspections & troubleshooting

When something feels wrong but the cause is unclear, we inspect the system, gather evidence, and explain what we find.

Permit-related plumbing work
64

Permit-related plumbing work

When permits and inspections are part of the job, we complete the plumbing scope so the work is ready for the inspector.

The Evidence
  • Corrosion at the base of the tank
  • Age past a typical service life
  • Moisture limited to the heater closet
The Investigation
Private I Plumbing traced the water to the tank itself, not a supply line or a drain.
The Solution
The failed water heater was replaced, and the connections were redone correctly.
