What to do if your condensate pump is not draining

condensate pump not draining

If you've noticed a puddle forming around your heater or AC unit, you're likely coping with a condensate pump not draining correctly. It's one of these annoying household issues that usually jumps up right whenever you're relying upon your HVAC program one of the most. Whether it's the center of a humid summer or a freezing winter, the failing pump may lead to drinking water damage, mold, or even your entire program shutting down as being a safety precaution.

The good news is that this isn't always a "call the costly technician" kind of emergency. Frequently, the particular fix is some thing you can manage yourself with the few basic tools and a bit of patience. Let's walk through why these pumps cease working plus how you can get things flowing again without losing your mind.

Why is presently there water on my floor?

The job of a condensate pump can be quite simple. Your air conditioner or even high-efficiency furnace creates moisture as a byproduct of cooling or heating. That water drips into a water tank, and once it hits a certain level, the pump kicks in and pushes that drinking water via a plastic tube to a drain, a laundry sink, or even even outside.

When you notice a condensate pump not draining , the water has no place to go yet over the sides from the tank. Just before you panic, take a look at the area. Will be the water coming through the pump by itself, or is really a pipe leaking? When the tank is full towards the brim and the particular pump is quiet, you've found your own culprit.

The particular common suspects at the rear of a failed pump

In my experience, these little pumps are usually quite dependable, but they reside in a wet, dark environment—which is definitely basically a play ground for gunk. There is a handful of factors why the pump might choose to consider a day off.

Sludge plus algae buildup

This is the particular number one reason for a pump failing. Because the water sitting in that will tank is often lukewarm and stagnant regarding short periods, it's the perfect reproduction ground for "white slime" or algae. Over time, this stuff turns into a thick jelly that clogs the consumption of the particular pump or will get stuck in the mechanised parts. If the pump can't "inhale" the water because of a wall of slime, it's not going to strain anything.

A stuck float switch

Inside the particular pump tank, there's a small plastic drift, much like the one within your toilet container. As the water rises, the float rises. Once it hits a particular height, it flips a switch that tells the electric motor to begin. If this particular float gets stuck—either because of the aforementioned sludge or just mechanical wear—the motor will never know it's time to obtain to work. You might have a tank overflowing while the pump sits there quietly, completely unaware this has a job to do.

The check valve is jammed

Many pumps have an one-way check valve in which the discharge tube connects. This device prevents water through flowing back straight into the pump once the motor becomes off. Sometimes, a tiny piece of debris gets wedged in there, or maybe the device just gets gummed up. If it's stuck shut, the motor might be hum and strain, but no water will be going anywhere.

How to troubleshoot a condensate pump not draining

Before you start taking points apart, let's do some basic bank checks. Sometimes the repair is so simple you'll feel silly for even considering it.

  1. Check the power: It sounds obvious, but make sure the pump is actually plugged in. Occasionally these get bumped, or a GFCI outlet trips. When there's no energy, there's no pumping.
  2. Give it a "tap": Sometimes the motor or the float simply needs a little nudge. A gentle tap on the side of the tank can occasionally break the top stress of the crud and get things moving. If this starts up, you know you need in order to clean it soon.
  3. Examine the safety change: Most modern pumps are born into the HVAC system's "low voltage" line. If the pump overflows, it trips a switch that shuts lower your AC or furnace to avoid more water production. When your AC offers mysteriously stopped working along with the particular pump issue, this particular is likely the reason why.

Getting your hands dirty: Cleaning the pump

When the basics didn't work, it's period to clean the unit. You'll wish to turn off the particular power to your HVAC system and unplug the pump just before you start. Have got a bucket and some towels convenient, because things are usually about to get wet.

First, disconnect the empty lines coming from your furnace or AC. Then, meticulously remove the pump unit. Most of them possess a best part (the electric motor and electronics) that will snaps onto a bottom reservoir. End up being careful not to bend the drift arm when a person pull it aside.

Take the reservoir tank to a sink and give it a good scrub with cozy, soapy water. When it's really nasty, a small amount of bleach or even white vinegar may help kill off the mold plus algae. While you're at it, check the intake hole within the bottom of the motor assembly. In case there's a clump of hair or dust in right now there, pull it away.

Testing the particular float and electric motor

As you have the pump aside, you can test the float manually. Plug the pump back in (carefully! ) and raise the float along with your finger. You ought to hear a distinct click , and the engine should roar to life. If the particular motor sounds like it's struggling or even making a milling noise, it might be time regarding a replacement. These pumps aren't usually worth repairing at a component level; if the motor is shot, you're better off buying a new unit for $50 or even $60.

Dealing with a blocked discharge line

If the pump is running but the water isn't relocating, you've probably obtained a clog in the discharge tubing. This is actually the long, clear plastic material hose that network marketing leads away from the unit. These lines may get surprisingly connected up with mineral deposits or algae.

You can try to blow out the line if it's brief, or use a wet/dry vac upon the far end of the pipe to suck out your obstruction. If the particular line is various years old and looks brown or opaque, it might simply be easier in order to head to the equipment store and buy a new move of vinyl tubing. It's cheap, and it'll save you the headache of seeking to clean twenty feet of thin pipe.

Precautionary maintenance is your own best friend

Once you've solved the mystery from the condensate pump not draining , you'll make sure it doesn't happen again next month. The best method to do this is by using regular maintenance.

  • Vinegar Flushes: Every few weeks, pour some white vinegar into the pump's reservoir. This helps maintain the pH degree in a range that prevents algae from growing.
  • Algae Tablets: You can purchase specialized condensate pan tablets with most diy stores. A person just drop one particular in the container, and it also slowly dissolves, keeping the drinking water clear of slime.
  • Yearly Cleaning: Make it a habit to the particular pump apart once a year—maybe once you change your furnace filters—and give this a quick wipe down.

When in case you just replace the pump?

If your pump is more than five or six years older and it starts acting up, I usually recommend just changing the whole thing. They are relatively inexpensive, and as soon as the motor begins to weaken or the plastic will become brittle, you're just living on borrowed time.

Replacing it is definitely usually a DO-IT-YOURSELF job. You just need to in order to make sure the new pump has the same "lift" rating (how higher it can press water vertically) because the old a single. Most standard house pumps have a fifteen to 20-foot raise, which is lots for a basements installation.

Dealing with a condensate pump not draining is never ever fun, specially when you're worried about your floors. But simply by staying on top of the cleanup and understanding how in order to spot a trapped float, you may keep the basement dried out as well as your HVAC system running smoothly. It's just one of those little "homeowner chores" that pays off in the long run.
