A Deep Dive Into Plumbing Diagnostics in Southern Idaho

When something’s wrong with your plumbing, it’s not always obvious what’s causing the issue—or how bad it really is. That’s where a professional plumbing diagnostic from On The Ball Plumbing comes in. Think of it like a full physical for your pipes, fixtures, and water systems. Whether you’ve got a mystery leak, recurring clogs, or just want peace of mind, our diagnostic services are designed to give you clear answers.

But what exactly does a plumbing diagnostic include? And why is it worth your time and money?

Let’s take a deep dive into what happens during a plumbing diagnostic and how homeowners in Twin Falls and throughout the Magic Valley benefit from this essential service.

What Is a Plumbing Diagnostic?

A plumbing diagnostic is a thorough evaluation of your plumbing system. It goes beyond surface-level problems to identify root causes. It involves a mix of visual inspection, physical testing, and sometimes specialized tools like camera scopes or pressure gauges.

On The Ball Plumbing approaches diagnostics with one goal in mind: identify the problem quickly and accurately so we can fix it right the first time.

It’s ideal for:

• New homeowners who want a full system check-up
• Repeat plumbing issues with no clear cause
• Emergencies when something suddenly goes wrong
• Annual maintenance to prevent major failures

Step-by-Step: What’s Included in a Plumbing Diagnostic?

1. Initial Interview with the Homeowner

Before we even pick up a wrench, we start by listening. We’ll ask about:

• When the issue started
• What you’ve noticed (sounds, smells, visible leaks)
• Which fixtures or drains are affected
• Any DIY fixes that have been tried

This gives us context and clues before we inspect your home.

2. Whole-Home Visual Inspection

Our techs perform a full walk-through to assess the condition of:

• Pipes (exposed and accessible)
• Fixtures (toilets, sinks, showers, tubs)
• Valves, shut-offs, and hose bibs
• Water heater (including age, rust, and pressure relief valve)
• Signs of leaks in walls, ceilings, or crawl spaces

We’re not just looking for active problems—we’re looking for warning signs that something might go wrong soon.

3. Water Pressure Testing

Water pressure that’s too high or too low can wreak havoc on your plumbing system. Using a pressure gauge, we’ll measure PSI at several points in your home to ensure it’s within the safe range (typically 40–80 PSI).

Signs of pressure problems:

• Banging pipes (water hammer)
• Sudden temperature swings
• Slow-filling appliances

If needed, we’ll inspect your pressure-reducing valve (PRV) and recommend adjustments or replacements.

4. Drain and Sewer Line Evaluation

A. Drain Flow Testing

We’ll test how quickly and consistently water flows from various drains—sinks, tubs, showers, and toilets.

Slow drainage or bubbling may indicate:

• Partial clogs
• Improper venting
• Bellied pipes

B. Camera Inspection (If Needed)

For persistent drain issues, we use advanced camera equipment to inspect your main sewer line. This reveals:

• Root intrusions
• Cracked or collapsed pipes
• Grease build-up
• Orangeburg piping (common in older Twin Falls homes from 1945–1970)

If your home still has Orangeburg sewer lines, you could be at risk for a complete collapse—our camera scope catches this before disaster strikes.

In neighborhoods like Kimberly, Filer, and downtown Twin Falls, we often uncover aging sewer lines that have shifted or deteriorated due to silt loam soil, freeze-thaw cycles, or long-term settling.

5. Leak Detection

Even a tiny leak can waste thousands of gallons of water—and hundreds of dollars. Our diagnostics include a pressure check of your system to see if you’re losing water somewhere unexpected.

We’ll also inspect for:

• Slab leaks (especially in older homes without basements)
• Leaks behind walls or under sinks
• Toilet tank and flapper seal leaks

In some cases, we use acoustic leak detection or infrared thermal imaging to pinpoint hidden leaks without tearing into your walls.

6. Appliance & Fixture Checks

Fixtures get a lot of use—and can cause sneaky problems. During your diagnostic, we’ll inspect:

• Toilets (checking for ghost flushing, running, and weak flushes)
• Faucets (drips, mineral build-up, weak flow)
• Shower valves (for leaks or temp inconsistencies)
• Washing machine hookups (for hose wear or improper sealing)

We’ll also take a look at your water heater, checking for:

• Signs of corrosion or rust
• Sediment build-up
• Water temperature accuracy
• T&P valve condition
• Age of the tank (and whether it’s time for a replacement)

If your home uses a tankless system, we’ll inspect:

• Flow sensors
• Heat exchanger condition
• Error codes or service indicators

What Happens After the Diagnostic?

Once our evaluation is complete, you’ll receive:

• A detailed report of what we found
• Photos or video (especially if a sewer scope was used)
• Priority list of recommended repairs
• Transparent pricing for any suggested work

You can choose to:

• Have repairs completed the same day (in many cases)
• Schedule future service
• Get a second opinion (we’re confident in our findings!)

And if your issue turns out to be simple or easily fixed—we’ll tell you that too. No pressure. No upselling.
