Tankless Water Heater Installation
Service, descaling, sizing and replacement for the dominant equipment here.
Tustin Legacy: 92782
Plumbing for new construction, which fails differently
Tustin Legacy is built on the old Marine Corps Air Station, and almost nothing here is old enough to corrode. The calls are appliance-side and installation-side: tankless units, softeners, regulators, and the specific faults that show up in the first ten years of a house rather than the last thirty.
- New-construction homes and townhomes
- Tankless and high-efficiency equipment
- Warranty-era fault diagnosis
Tell us the builder and the year, it matters more than you would think.
A different problem set
What actually goes wrong in a ten-year-old house
New houses do not have corrosion problems. They have installation problems, appliance problems and specification problems, and those three account for nearly everything we see in Tustin Legacy.
Installation faults surface in the first few years: a fitting that was never fully seated, a vent run that is technically compliant and functionally marginal, a pan drain that terminates somewhere unhelpful. Appliance faults follow, tankless units that were sized for the brochure rather than the household, softeners that were never commissioned properly, recirculation pumps running on a schedule nobody set.
And then there is pressure. New developments frequently deliver street pressure well above what the fixtures inside are rated for. The regulator handles it until it does not, and the first sign is often a failed supply line rather than a gauge reading anyone took.
Common in newer Legacy homes
- Tankless unit short-cycling or throwing an error code
- Hot water that takes noticeably longer than it used to
- Softener that regenerates constantly or never
- Water hammer on shutoff, especially at the washer
- Static pressure over 80 psi at the hose bib
None of these mean the house is bad. All of them get worse if left.

Legacy in detail
Where the work concentrates
Tankless service and descaling
Tankless water heaters are the norm across much of Legacy and they are the single most common service item we handle here. They are not maintenance-free. Local water chemistry scales the heat exchanger, and a unit that has never been flushed will lose output, short-cycle and eventually fault. Annual descaling is genuinely the difference between a fifteen-year unit and an eight-year one, and it is a straightforward job, not a sales pitch dressed as maintenance.
Softeners and filtration
A large share of Legacy homes have a softener loop roughed in, and a good number have units that were installed but never properly commissioned, wrong hardness setting, wrong regeneration schedule, or bypassed entirely by someone who did not know what the valve did. Getting the settings right is often the whole job. Where the unit itself is undersized for the household, we will say so and price the alternative rather than tuning something that cannot keep up.
Townhomes and attached construction
Attached homes share walls, and sometimes share more than that. A leak on one side becomes a neighbour’s problem quickly, and the shutoff you need may not be the one in your unit. On townhome calls we locate and confirm the isolation points first, before any work starts, it is the step that prevents a small repair becoming an HOA incident.
Book a tankless descale before it faults
Cheaper as maintenance than as an emergency. Considerably.

Local practicalities
Warranties, builders and who to call first
If your house is still inside a builder warranty period, call the builder first for anything that looks like an installation defect. We will tell you when something reads that way rather than quietly doing work you should not be paying for. That is not us turning away business; it is the correct order of operations.
Outside warranty, or for anything appliance-side, the builder is usually not the right call anyway. Manufacturer warranties on tankless units and softeners often survive longer than the builder’s, and they typically require documented service history, which is a good reason to keep the paperwork from every visit, ours included.
Garage and utility-closet installations dominate here. Access is generally good, which keeps labour time down. Where a unit is in a tight closet with marginal clearance, we will tell you what the replacement options actually are before you shop for one that will not fit.
Ask about a maintenance interval that makes sense
We will tell you what genuinely needs an annual visit and what does not.
Worth doing in a newer house
Descale the tankless annually: or every two years on a light-use household. It is the highest-return maintenance item in this neighbourhood by a distance.
Check the softener is actually working: a bar of soap tells you more than the display does. If it will not lather, the unit is not doing its job whatever the panel says.
Gauge the pressure once: new developments run high. Knowing your number takes five minutes and can explain three unrelated symptoms.

Questions from this neighborhood
Tustin Legacy questions
Because the failure modes of a new house are installation and appliance faults, not corrosion. A fitting that was never fully seated will find you in year three. A tankless unit that has never been descaled will lose output by year five. Age protects you from some problems and not others.
In this water, yes. Scale accumulates on the heat exchanger and the unit compensates by working harder until it cannot. Manufacturers specify it, and most warranties assume it. If someone tells you a tankless is maintenance-free, they are selling you the unit, not servicing it.
Builder first if you are inside warranty and the fault looks like installation. Us for anything appliance-side, anything outside warranty, and anything urgent at two in the morning. We will tell you which category yours falls into on the phone.
It is worth checking. Units that were never commissioned to the actual water hardness either regenerate far too often, wasting salt and water, or not enough, in which case you have a softener that is not softening. Both are cheap to correct and expensive to ignore.
Common, not normal. It is usually a missing or waterlogged arrestor combined with high pressure, and it is worth fixing because the shock is doing cumulative damage to every joint in the system. It is a small job.
That depends on your CCRs and we will not pretend to interpret them for you. What we will do is establish exactly where the leak originates and give you documentation that says so, which is the thing you need before that conversation starts.
