When water starts coming through the ceilings of a newer building, carriers call it a maintenance problem. AMPR Consulting proves the plumbing defects and HVAC installation failures behind it, fronts the testing costs, and coordinates the experts and counsel.
Leaking Shower Pans and Ceiling Leaks Usually Point to Plumbing Defects
Most calls start with water leaking from a ceiling in an apartment below a bathroom or mechanical closet. One crew installs every shower pan, drain, and condensate line with the same methods, so a defect in one unit usually repeats across floors. The damage hides in walls and ceilings until it surfaces in the unit below.
The defects AMPR documents most:
Plumbing Defects
- Improper shower pans: No layered pan and mortar bed, or waterproofing coated directly on the subfloor.
- No-hub drain couplings: Under-torqued or misaligned connections that leak inside chases and ceilings.
- CPVC piping errors: Improper support, no allowance for expansion, or contact with incompatible chemicals in firestop, insulation, and cabling.
- Non-conforming valves and fittings: Unlisted parts that fail early.
- Missing hot water insulation: Uninsulated domestic hot water and recirculation lines.
HVAC Defects
- Condensate lines: No slope or traps, and no secondary drain pan or float switch above finished ceilings, as the mechanical code requires.
- Improper HVAC installation: Undersized equipment, leaky ductwork that fails Title 24 testing, and thermostats that can’t regulate temperature.
Three Carrier Arguments Against Plumbing Claims and How AMPR Counters Them
The same arguments show up across water intrusion construction defect claims. AMPR is not a law firm. AMPR builds the technical record and coordinates with counsel, who make the policy arguments.
“It’s a maintenance issue.” AMPR counters with code and spec violations, failures in the first years of occupancy, the same failure repeating across units, and defects concealed where no maintenance program could reach. AMPR also collects your maintenance records early to close off the argument.
“Only the faulty plumbing is defective.” The “your work” exclusion may reach the condensate line or shower pan itself. AMPR documents the soaked ceilings, drywall, and flooring below as resulting damage, time-stamped to the right policy period.
“Mold is excluded, and your damages are a rough estimate.” AMPR documents the loss as water damage caused by the defect, with mold as the consequence. An independent cost report and forensic accountant backup replace any rough estimate.
Frequently Asked Questions About Plumbing Defect Claims
The carrier says our leaks are a maintenance issue. How do we push back?
With evidence the carrier can’t explain away: code violations, early failures, and the same defect across units. AMPR collects your maintenance records up front so the argument has nowhere to land. Learn how to tell a construction defect from wear and tear.
Leaks keep showing up in different units. Is that one claim?
Usually. Repeated shower pan or drain leaks across floors point to one installation method, not separate accidents. Here’s how to tell an isolated repair from a building-wide defect.
Our AC units are leaking water from the ceiling. Is that a construction defect?
Often, yes. Condensate lines without slope or traps, and missing secondary drain pans above finished ceilings, are installation defects. See what is a construction defect for where the line falls.
Will the builder’s insurance pay to replace the shower pans or piping?
Liability policies generally pay for the damage defective work caused, not the cost of redoing the work itself. That’s why AMPR documents every ceiling, floor, and finish the water reached. Recovery often turns on your builder’s risk and wrap-up policies.
How do you value damage to the units below?
AMPR scopes every affected area, prices it through an independent cost estimator, and has a forensic accountant tie lost rent and relocation to your rent rolls. Here’s what your construction defect claim is actually worth.
Should we open the walls and repair now?
Stop active leaks right away, but don’t tear out pans or piping until the carriers can inspect. Discarded evidence weakens the claim. Read what to do in the first 48 hours.
What does it cost, and how long does it take?
The first conversation costs nothing, and engagement terms are discussed openly at that stage. Timing depends on the building, the number of carriers, and how quickly testing can be scheduled, and many matters resolve without a lawsuit. AMPR typically handles claims with $1 million to $40 million in defect damage. Here’s what a construction defect investigation involves.
Do we need to sue the builder?
Often, no. Many of AMPR’s matters resolve through mediation before any lawsuit. Filing first usually triggers cross-complaints and years of discovery, which is what hiring an attorney before a consultant costs you.
Does this apply to HOAs, insurers, and contractors?
Yes. Boards can get HOA construction defect support when leaks cross between units. Insurance professionals get a lab-backed record for coverage decisions. Contractor defect claims benefit from testing that separates installation failure from misuse. Owners and developers of newer multifamily buildings bring AMPR most of its plumbing work.
