Plumbing Repairs in Pleasant Hill, IA

By Jarod Smith, Owner, Clog Busters. 26 years in plumbing and drain cleaning. Updated October 2026.

A faucet that keeps dripping or a water heater valve that weeps onto the floor usually has a cause you cannot see. Our plumbing repairs in Pleasant Hill start by finding that cause, then fixing the part that failed and the problem behind it.

We at Clog Busters Drain Cleaning & Repair work in homes across Pleasant Hill, from the Copper Creek Lake area to the streets along Four Mile Creek. Book service online and we will walk you through your options before any work begins.

Plumbing Repairs Pleasant Hill Homeowners Call Us For

Most repair calls fall into a handful of patterns. These are the ones we see most in the area.

• Dripping relief valves. A relief valve that drips or runs is a warning, not a nuisance. We find the pressure problem behind it and replace the valve if it no longer seals. Problems inside the tank itself are covered on our water heater repair and replacement page for Pleasant Hill.
• Expansion tank replacement. An expansion tank absorbs the extra water a heater creates as it warms up. Once its air cushion fails, the tank fills with water and stops protecting your pipes. We check it and replace it when it has failed.
• Pressure reducing valve repair. A pressure reducing valve, or PRV, lowers the pressure entering your home from the street. A worn PRV lets pressure creep up and strains every fixture. We confirm the fault before we replace anything.
• Faucet and sink repair. Worn cartridges, washers and supply connectors cause most sink leaks. We replace the failed part or the faucet, then check every connection under the sink.
• Low shower pressure repair. Weak flow at one shower often points to a failing valve or corroded pipe behind the wall. We trace the restriction and replace what is causing it.
• Toilet repair. Running or rocking toilets usually need a new fill valve, flapper or wax seal. We tell you when a repair makes sense and when replacing the toilet costs less over time.
• Leaking and burst pipe repair. We open only the area we need, cut out the damaged section and restore the line. If water is spreading right now, our 24/7 emergency plumbing service in Pleasant Hill is the faster route.
• Shutoff valve replacement. Fixture stops and main shutoffs that will not close fully get replaced before they fail during the next repair.

Why Relief Valves and Fixtures Leak in a Closed Water System

Water grows in volume as it heats. In an open system, that extra water can push back toward the public main. When a check valve, pressure reducing valve or backflow preventer sits on your water service, the extra water has nowhere to go.

The 2024 Uniform Plumbing Code, which Iowa adopted in 2025, treats this as a closed system and requires an approved way to control thermal expansion, such as an expansion tank.

Here is what a closed system does inside your home:

• Each time the water heater recovers, pressure in the tank and pipes climbs.
• The temperature and pressure relief valve, which the guide says is normally preset at 125 or 150 psi, starts to weep.
• Faucet cartridges, toilet fill valves and supply connectors absorb repeated pressure spikes and wear out early.

The standard fix is a working expansion tank. The guide describes it as a small tank with a sealed, compressible air cushion that stores the expanded water. When that air charge is gone, the system behaves as if no tank were installed.

That is why we treat a dripping relief valve as a symptom. Before we replace fixture parts in a Pleasant Hill home, we check whether the water service is closed, whether an expansion tank is present and whether it still holds its charge. Solving the pressure problem first keeps new parts from failing early.

Recent Repair Jobs, in Our Customers’ Words

A water heater checked and back in service

Janelle Manor’s water heater was not working the way it should. Dylan and Anthony came out to look over the whole unit and get it running again.

Janelle Manor wrote: “Dylan and Anthony did an awesome job they did a thorough check of my water heater and got it working beautifully thank you again Dylan and Anthony if I hear of friends or family that are needing work done in their home I will definitely recommend you gentleman and your company.”

The water heater is where thermal expansion problems usually show up first, so a careful look at the tank and the valves around it is time well spent. Read this review on Google

Low shower pressure that turned out to be more than one part

A customer named Austin had weak cold water pressure in an apartment bathroom shower. The cause went well past a single worn part.

Austin wrote: “Noah and Lukus came to my apartment to fix my cold water pressure in my bathroom shower. Turns out that most of the actual pipes and faucets needed replaced and they knocked it all out without any issues!”

Low pressure at one fixture is often a sign of a larger problem behind the wall. We find the real cause, explain the choices and fix it with parts carried on our trucks whenever we can. Read this review on Google

Questions About Plumbing Repairs in Pleasant Hill

Why does the relief valve on my water heater drip?

The most common cause is thermal expansion in a closed system. If your Pleasant Hill home has a check valve, PRV or backflow preventer on the water service, heated water cannot push back to the main, so pressure builds until the relief valve opens. A failed or missing expansion tank is the usual culprit.

Is a dripping relief valve safe to ignore?

No. The relief valve is a safety device, and a valve that opens every day wears out. We replace a worn valve and fix the pressure problem behind it, so the new valve is not doing the same job again within months.

Can you repair a leak the same day in Pleasant Hill?

We offer same day service, and our crews work out of our Des Moines branch, a short drive from Pleasant Hill. When water is actively spreading, use our 24/7 emergency service instead of waiting for a regular appointment.

Should I repair or replace an older faucet?

If the body is sound and parts are available, a new cartridge or washer usually solves the leak. If the finish is failing, parts are hard to find or the faucet has leaked at more than one point, replacement often costs less over time. We give you both options with prices.

How do I know if my repair is part of a bigger problem?

Repeated leaks at different fixtures, low pressure in several rooms or rusty water point to something system wide. A plumbing inspection in Pleasant Hill reviews supply lines, valves and the water heater together, so you can plan repairs instead of reacting to them.
