Ever woke up with a water that just won’t drain? Well, it must be one of the worst things to wake up to. If you’re like me who isn’t naturally fond of learning the ways around my home, then you’re in for a treat.
You may ask: how do you remove the sediments when it’s not draining? Let me tell you, you are definitely not alone. A lot of the water heaters, especially the older models, do not have an anti-sediment feature. There are basically two main ways to unclog the drain:
Hot water procedures
With these methods, there’s no need to cool off the tank. Just make sure to be careful and wear protective gears if available because this may pose some burn risks.
- Back flushing
Here, you will be needing to get your hands on a washer fill hose. It has connections on opposite ends. Just attach the drain valve to one end and the wash tub or a faucet to the other. After this, the drain valve should be opened. Lastly, turn the water on.
The water pressure generated by the hose will push the sediments and eventually, will unclog your heart. Wait for approximately two minutes then shut if off, close the valve, take the hose out and let it drain.
- Hose stomping
If the drain, which is a two-way valve, clogged prior or while you are trying to drain, just stomp your foot forcefully on the hose so that a huge chunk of air will make its way to the tank. This will push away the sediments. You may repeat the stomping until you see your water flowing freely. However, this is not applicable to kink-proof hoses. But, if you have the standard ones, this should do the trick.
- Some patience
Chances are: your heater may unclog on its own. The waiting time may take until an hour or two but this need not be closely monitored. Checking back in once in a while should suffice.
Well obviously, this method is the most time-consuming and the one with the least effectiveness. Additionally, it might not work against heavy sediment congestion.
Cold water procedures
With cold water methods, you have to be extremely near the drain valve. Because of this, we recommend that your hot water tank should be shut off for up until a whole day.
- Hanger method
This method is tedious so make sure to protect your floors with some towels. First, open the drain valve and put the coat hanger’s wire in. As it enters the valve, allow it to move in circular motions in the hopes of hitting and dislodging the sediments.
Once the water starts to flow out, turn the drain valve off to attach the hose. Repeat as needed.
- Replacement of drain valves
The clogged water heater isn’t always the one to blame. A malfunctioning drain valve may be the culprit and if so, you would have to replace it. Before starting the process, make it a point that all faucets around your home are turned off. This is to prevent air from entering the tank as you work.
To start, get the new valve and put on some teflon tape to its threading for waterproof sealing. Then, remove the screws of the defective valve and prepare for some possible leakage. After which, quickly take it out and put the new one in. And there you have your new drain valve!
- Open flushing
Should you have a floor drain situated just beside your heater, you may opt to just take the drain valve out and let the water flow. After which, you may start to fish with, again, the use of an ever-so-reliable coat hanger. This is extremely tedious, but may be one of the most effective if done properly.
And there you have it! Now, you have six ways to choose from if you find yourself with a clogged heater again.
