Rheem Water Heaters in Waukee and Central Iowa
Rheem is one of the most common water heater brands in the country, and many Iowa basements have one humming away in a corner. The brand makes gas and electric tank water heaters, tankless units, and hybrid heat pump models that use less power. Because so many homes have a Rheem, parts are easy to find and the usual repairs are well known.
We are an independent plumber. We are not part of Rheem and do not speak for the company. We stock common parts and know the usual fixes, and we will give you honest advice on whether to repair or replace. Call +1 (515) 585-4137 if your water heater is acting up.
A standard tank heater is simple. Cold water enters through a dip tube and falls to the bottom of the tank. A gas burner or electric heating element warms it. A thermostat keeps the temperature steady. Hot water leaves from the top. An anode rod inside the tank attracts corrosion so the steel tank lasts longer. A temperature and pressure relief valve is the safety part that opens if pressure gets too high.
When any one of those parts wears out, you notice. The water may go lukewarm, run out too fast, make loud noises, or leak. Knowing which part failed tells us whether a repair will do.
Common Rheem Problems We Fix
- No hot water because of a failed element or thermostat on an electric unit.
- A pilot light that will not stay lit on a gas unit.
- Rumbling or popping from sediment in the tank.
- Rusty or smelly hot water.
- A leaking relief valve or drain valve.
- Water pooling around the base of the tank.
No Hot Water or Not Enough
On an electric Rheem, there are usually two elements, one near the top and one near the bottom. If the top one fails, you may get no hot water at all. If the bottom one fails, the hot water runs out quickly. A tripped breaker or a reset button on the thermostat can also be at fault. We test power, test each element, and replace what is bad.
On a gas model, the cause is often the thermocouple, the gas valve, or a dirty burner. A pilot that keeps going out is a clue. We clean the burner, check the flue draft, and replace parts that have worn out. Safety is first. If you ever smell gas, leave the house and call your gas company from outside. Do not try to relight anything. If it happens at night, see our 24/7 emergency plumbing page.
Noise and Sediment
Popping and rumbling mean sediment has settled at the bottom of the tank. Iowa has hard water, and minerals fall out of it as it heats. The layer traps water under it, which boils and bubbles up through the crust. That is the sound. Sediment also makes your heater work harder and can overheat the tank bottom. On electric models it can bury the lower element.
Flushing the tank helps. We drain it, stir up the sediment, and rinse it out. If the heater is quite old and the crust is thick, flushing may not remove it all. In that case, replacement may be the better value. Read our repair or replace water heater article to see the signs.
Choosing the Right Rheem Model
Size matters most. A heater that is too small leaves the last person in the shower with cold water. One that is too big wastes energy. Count your bathrooms and think about how many people shower in the morning. Add the dishwasher and the washing machine. A family of five needs more than a couple does.
Tank heaters are rated by gallons and by how fast they recover. The first-hour rating tells you how much hot water you can get in an hour of heavy use. Look at that number, not just the tank size. We help you read the label and match it to your life.
Next, choose the fuel. Natural gas heaters recover quickly and often cost less to run. Electric heaters are simple to install, with no vent needed. Hybrid heat pump models are very efficient, but they need space and some airflow, and they cool the room a bit. Tankless units never run out of hot water but need a larger gas line and special vent. See our pages on Navien and Rinnai for more on tankless.
Check the space. A tall tank may not fit a low basement ceiling or a tight closet. Think about where the vent runs and where the drain is. In Iowa, a basement location is normal. A drain pan and a nearby floor drain can limit water damage if the tank ever leaks.
How We Install and Repair Rheem Heaters
We begin with a look at the unit, its age, and its record. We check the venting, gas line or wiring, and the shutoffs. Then we give you a clear price before we begin, with options if they exist.
For a replacement, we shut off the supply, drain the old tank, and disconnect it. We set the new heater, connect water with new flex lines or copper, and add a proper relief valve with a discharge pipe. Many homes also benefit from an expansion tank, which absorbs pressure when water heats up. We vent the unit, connect gas or power, fill the tank, and test for leaks and safe operation.
Afterward, we show you where the shutoff, thermostat, and drain are, and set the temperature. A setting near the middle range balances comfort with safety and energy use. Our water heater installation and repair page lists the full service.
Signs Worth Acting On
- Rumbling or popping sounds from the tank.
- Water that never gets hot, or runs out fast.
- Rusty water from the hot tap.
- Puddles or dampness near the base.
- A heater that is many years old and shows rust on the tank.
Leaks from the tank itself cannot be repaired. Once the steel is rusted through, the tank must be replaced. Shut off the water to the heater and the gas or power, and call us. Do not wait, since a small drip can turn into a flood overnight.
Care Tips for Rheem Heaters
Flush the tank once a year. That clears the sediment that makes noise and wastes energy. Test the temperature and pressure relief valve by lifting its lever briefly, with a bucket or drain pipe in place. If it does not seat tightly afterward, or if it does not release water at all, it needs replacing.
Check the burner or elements before winter. A gas heater should have a steady blue flame. A yellow or flickering flame may mean a dirty burner or poor air. Look at the area around the heater for dust and stored items. Keep it clear.
The anode rod is a smart item to check. It wears away so your tank does not. When it is mostly gone, the tank starts to rust. Replacing it can add years to the heater. Ask us about checking it during a flush. A water softener also helps. It means less scale in the tank and less wear on parts.
Set the thermostat at a safe level to avoid scalds, especially if children are at home. If you will be gone during a cold snap, keep the house heated so pipes near the heater do not freeze. Our frozen pipe guide has more.
Repair or Replace?
Repair is wise when the heater is fairly young and the failure is a single part, like an element, a thermostat, or a gas valve. Replace when the tank leaks, when the unit is near the end of its usual life, or when repairs pile up. A heater that is many years old and starts to fail often is not worth much more investment.
Cost depends on the type of heater, the size, and the changes needed for venting, gas, or electric. Moving the unit or adding an expansion tank changes the price. We give you the number first and explain each line.
Check your paperwork. Many water heaters come with a limited warranty, often with longer coverage on the tank than on parts, and the terms differ. Find your receipt and the label on the tank, which has the model and serial number. If your heater is still covered, contact the maker about the claim. We can document what we find.

Questions We Hear Most
Do you service Rheem?
Yes. We repair and install Rheem products and can advise on a good model for your home. We are an independent plumber, so we do not push one brand.
Why is my Rheem heater making popping noises?
That sound is usually sediment at the bottom of the tank. Flushing often helps. If the tank is very old, replacement may be the better choice.
How often should I flush my water heater?
Once a year is a good habit. Hard water homes may benefit from more often. It keeps the heater efficient and helps it last.
Should I choose gas, electric, or hybrid?
It depends on your fuel, space, and budget. Gas recovers fast, electric is simple, and hybrid saves power but needs room. We can compare them for your home.
Is a leaking water heater an emergency?
If the tank itself leaks, yes. Turn off the water, gas or power, and call us right away. A small leak can become a flood.
