Unstable water pressure can be a frustrating problem to deal with, leaving us feeling helpless and inconvenienced. One common culprit behind low water pressure is a malfunctioning check valve. A check valve is designed to allow water flow in one direction while preventing backflow. However, over time, these valves can become stuck, resulting in restricted water flow and diminished pressure.
In this blog post, we will explore the different reasons why a check valve can become stuck and how to address the issue. From understanding the causes of check valve failure to learning how to manually open a seized valve, we will equip you with the knowledge to tackle this problem effectively. So, if you find yourself struggling with low water pressure, read on to discover the methods and techniques to unstick a check valve and restore normal water flow.
How to Unstick a Check Valve
Have you ever encountered a stubborn check valve that just refuses to budge? Well, fear not! In this guide, we’ll walk you through some ingenious tricks to unstick that valve and get things flowing smoothly again. So put on your problem-solving hat and let’s dive in!
1. Tap it: Give it some love
Sometimes, all a check valve needs is a little gentle persuasion. Grab a wrench and give it a few taps to loosen any debris or sediment that might be causing the blockage. Just remember, we’re going for a love tap here, not a Hulk-style smash!
2. Heat it up: Get things steamy
Heat can be a check valve’s best friend when it’s feeling stubborn. Grab a hairdryer and aim warm air at the valve. The gentle heat helps to expand the metal, loosening any tight spots. Just be careful not to overdo it and let the valve dance like a salsa champion!
3. Coat it: Slippery when lubricated
If your check valve is as stuck as a kid in a candy store, it might benefit from a little lubrication. Grab some plumber’s grease or WD-40, and carefully apply it to the moving parts of the valve. Just remember, a little goes a long way – it’s not a buttering contest!
4. Shock it: Give it a shake
Sometimes, a stuck check valve needs a wake-up call. Grab that hammer (gently!) and tap the valve body a few times. The shockwaves help dislodge any stubborn debris. Just be careful not to channel your inner Thor and end up creating a plumbing disaster of thunderstorm proportions!
5. Reverse the flow: Turn the tables
If all else fails, it’s time to take desperate measures. Turn off the water supply and disconnect the check valve. Give it a good old-fashioned clean by running water through it in the opposite direction. This reverse flow can help dislodge any clogs and give the valve a fresh start. Just be prepared for a water show that rivals the Bellagio fountains!
6. Call the pros: Superheroes for your plumbing
If you’ve exhausted all your DIY tricks and the check valve is still as stubborn as a mule, it’s time to call in the professionals. Plumbers are like the superheroes of the plumbing world, armed with mighty tools and a wealth of knowledge. They’ll swoop in, fix the issue, and leave you marveling at their expertise.

Can you have two check valves on a sump pump
Two check valves on a sump pump, you say? Hold on there, eager beaver. While it might seem tempting to double up on the protection, most experts frown upon such behavior.
