Plumbing rarely fails without warning. It gives you months of small signals first — and the homeowners who catch them replace pipe on their own schedule instead of at midnight with water coming through a ceiling.
1. Water that runs discolored after the tap sits unused
Rusty or brown water on first draw, especially in the morning, usually means galvanized steel pipe corroding from the inside. The scale builds until it restricts flow entirely.
If it clears after a few seconds and only happens on first use, the pipe is the problem, not the municipal supply.
2. Pressure that has quietly dropped over years
Gradual pressure loss across the whole house points to internal buildup narrowing the pipe. It happens slowly enough that most people adjust to it without noticing until a guest comments on the shower.
3. A second pinhole leak
One pinhole leak is an incident. A second one in the same system is a pattern — the pipe has reached the end of its service life and patching individual spots becomes an expensive way to delay the inevitable.
4. Pipe material with a known expiry
Some materials simply have a shelf life, and knowing what is behind your walls tells you where you stand:
- Galvanized steel — 40 to 60 years, corrodes internally
- Polybutylene (grey plastic, 1978–1995) — prone to sudden failure, replace on sight
- Copper — 50+ years, but pinholes signal water chemistry issues
- PEX and modern copper — long service life when installed correctly
5. Water stains with no obvious source
A ceiling or wall stain that appears without a visible leak means water is traveling along framing before it surfaces. The actual leak is often several feet from the stain, which is why guessing at the location tends to open the wrong wall.
6. Drains that are slow everywhere at once
A single slow drain is a clog. Every drain in the house running slow points to the main line — root intrusion, a belly in the line, or partial collapse. Denver's older neighborhoods with mature trees see this regularly.
7. A water heater past twelve years
Tank heaters generally run 8–12 years. Past that, replacement on your schedule costs a fraction of replacement after the tank splits and floods a finished basement.
If two or more of these describe your home, it is worth having the system looked at properly. We provide free plumbing assessments across the Denver metro and will tell you plainly whether you are looking at a repair or a repipe.
