What we do
Water heater service
Repair, replacement, and the vent and pressure checks that catch problems a straight swap would miss.
Leak detection & repair
A wet spot, a rising water bill, or a hunch — the line gets traced before any wall or slab gets opened.
Drain clearing & hydro jetting
Slow drains and backed-up lines cleared with a cable or a jetter, depending on what's actually built up in the pipe.
Repipes & pipe replacement
Older galvanized or failing copper runs replaced in PEX or copper, section by section or whole-house.
Sewer camera inspection
A camera run down the lateral to see roots, bellies, or breaks before any digging starts.
Fixture & faucet install
Faucets, sinks, and disposals set, leveled, and leak-tested before the job is called done.

The name on the truck is the plumber in your kitchen
Pieper Plumbing is a Fallbrook plumber that explains the problem before it fixes it. That shows up in the small things: checking a water heater's venting instead of just swapping the tank, tracing a leak before opening a wall, walking you through what was found and why it matters. Homeowners in Fallbrook and the nearby valley call back with the next problem because the last one was explained, not just fixed. If something's wrong, you'll know what it is before you're asked to pay for the fix.

Diagnosis before the quote
The problem gets identified and explained before a number is given, not after work has started.
Plain answers
You hear what's wrong and what it will take in plain words, before you're asked to decide anything.
Show the failed part
Whatever gets replaced, you see the old part and the reason it failed.
How do you figure out what's actually wrong before quoting a repair?
By looking before guessing — tracing a leak with the right tools, running a camera down a sewer line, or checking a water heater's venting and pressure regulator rather than just swapping the obvious part. The explanation comes before the number.
Do you work on both older homes and newer ones?
Yes. Older homes in the area often still run galvanized pipe or aging water heaters, which get evaluated differently than newer copper or PEX systems. The approach follows what's actually in the walls, not a one-size fix.
How fast can you get out for a leak or a dead water heater?
Call and describe what's happening — active leaks and no-hot-water calls get prioritized over routine work. Scheduling is handled directly over the phone, not through a call center, so you get a straight answer about timing.
