Whole-Home Repipe & PRV in University Park, Irvine, CA

Whole-Home Repipe & PRV

Ideal for

• Repeated pinhole leaks or a growing history of slab patches

• Rusty first-draw water and weak pressure with two showers on

• Mixed galvanized → copper connections from past remodels/additions

• Insurance/inspection notes calling for a permanent, code-compliant fix

What we do/install

• Wet-wall mapping with attic/soffit routes to minimize openings

• PEX-A home-runs with isolation manifold, or Type L copper in exposed/mech areas

• New pressure-reducing valve (PRV) calibrated to 55–65 psi with documented readings

• Ball valves at fixtures, new angle stops/braided supplies

• Thermal expansion control; dielectric unions at heater/recirc points

• Restoration-ready close-ups; we handle drywall/texture/paint tie-ins

Why this neighborhood benefits

• Atrium/zero-lot plans respond best to a balanced manifold and correct PRV setting—quieter lines, steady temps, and fewer emergency callouts.

Typical timeline

• 1–2 bath homes: 1–2 days; larger/added-on homes: phase-by-phase with evening water-on whenever possible.

Slab Leak Detection & Restoration

When we recommend it: Single active leaks in otherwise serviceable piping, or as a bridge until a scheduled repipe. What it includes: Acoustic/thermal pinpointing, pressure isolation by zone, targeted overhead reroute or small-footprint slab repair, dry-out & build-back, and PRV verification. Why it fits here: Preserves tile/hardwood in atrium homes and stops damage quickly while planning a full repipe if warranted.

Neighborhood Issues We See Most

• Pinhole copper under kitchens/laundry from age/chloramines

• PRV drift → 80–100+ psi spikes stressing valves and supplies

• Long hot-water runs to additions/lofts → temperature lag

• Old galvanized scale throttling flow at multi-fixture demand

• Cast-iron to ABS transitions at garages causing slow drains (camera/jetting advised)

• Atrium plan near Sequoia: Warm tile + musty baseboards. Thermal locate → overhead reroute via closets/soffit; drywall/paint next day.

• Townhome off Michelson: Added office over garage. Repipe + condensing tankless w/ demand-recirc—hot water at far bath in ~20–30 seconds.

How We Work

Frequently Asked Questions

How fast can you get to University Hills (Irvine 92617) if our water heater fails and we’re out of hot water?

University Hills is typically a 20–30 minute ETA for us via I-405 and Culver/University, and we’re used to coordinating ICHA access and parking rules. If there’s an active leak from a tank, we can dispatch 24/7 emergency plumbing service and help prevent damage with 24/7 emergency water extraction while we plan the long-term hot-water fix.

Why do University Hills homes have long hot-water waits to upstairs baths, home offices, and guest suites?

A lot of University Hills plans are multi-story with long branch runs, so hot water cools in the lines between uses—especially to top-floor baths and remote wings. A properly engineered tankless water heater installation paired with a well-designed recirculation pump installation is the fastest way to reduce “cold start” complaints without wasting water.

Do I need a dedicated recirculation return line in University Hills, or can you do on-demand recirc?

Not always—many University Hills homes don’t have a true return line, especially if the layout has been modified over the years. We can often use on-demand options through a recirculation pump installation so far fixtures get hot water faster without running a new loop. Once it’s installed, we fine-tune comfort and stability with mixing valve commissioning and recirc balancing.

Will one tankless unit cover my whole University Hills home, or do I need a manifolded setup?

It depends on simultaneous use—morning rush with multiple showers, laundry, and kitchen demand can overwhelm an undersized “builder” tankless. We do load calculations and size the system so it matches real life, whether that’s one properly sized unit or a paired/manifolded tankless water heater installation for larger homes and multi-wing layouts.

Do University Hills homes usually need a gas line upgrade for a condensing tankless system?

Often, yes—tankless performance relies on correct gas sizing, especially in multi-story homes with longer runs and other gas appliances. We check load, piping, and venting, then handle upgrades through gas line repair and installation so the new system runs safely and consistently.

Is exterior venting allowed on University Hills hillside lots with ICHA/HOA guidelines?

Usually yes, but it has to be planned carefully so it’s discreet, code-correct, and compliant with community standards—especially on sloped elevations and tight side yards. We coordinate placement and routing as part of the tankless water heater installation and include any needed safety details like earthquake strapping and code upgrades.

How do you protect tankless heat exchangers from Irvine’s scale and keep the system quiet?

University Hills is a common “scale + noise” area, so we treat protection as part of the install—not an afterthought. Depending on preferences and ICHA rules, we’ll recommend water softener installation or salt-free conditioner installation, plus service-friendly valves and a bypass loop installation for easier maintenance.

What maintenance should I plan for a University Hills tankless + recirc system, especially with rarely used guest baths?

Annual service is the sweet spot here—flush the heat exchanger, verify gas/CO, confirm recirc performance, and keep filters/media in spec so you don’t get error codes or temperature swings. We make upkeep straightforward with tankless maintenance and flush service, and we can adjust the recirc strategy with mixing valve commissioning and recirc balancing to reduce stagnation and “rare-use” odor issues in guest baths.
