What’s the Difference between Hot Water Recirculating Pump and Regular Pump?
A standard pump and a recirculating pump look and work similarly. But they’re not the same thing. So, how do you tell a regular pump for a recirculation model? Simple, you do so by analyzing how it works.
For example, a typical pump has the only purpose of lifting or pumping water through plumbing systems. This lifting or pumping overcomes any pressure or gravity thanks to the motor’s power.
You can find regular pumps in wells, large buildings, residential homes, and more. They have the only purpose of pumping water from one end to the other. And they usually do this when the plumbing system alone is incapable of doing so.
But when we talk about recirculation pumps, we’re talking about a system that not only pumps but makes sure the water keeps circulating through the system.
The best way to put it simply is to compare it to a Ferris wheel. A recirculating pump pushes the water through the plumbing system, but the water returns to the same point if it’s not used. For that, the motor of a recirculating pump acts a little differently.
It doesn’t only pump water, but it also makes it run across the plumbing back and forth until it is used. In short, a standard pump pushes water through plumbing. In contrast, a recirculating pump makes water run through the pipes until it’s used.
Things to Consider before Buying Water Recirculating Pump
After reading our hot water recirculating pump reviews and learning the difference between them and standard pumps – it is now time to learn how to pick the right model. Here are a few factors to consider:
While most pumps come with the standard 3/4 connection system, you should still take a good look at the model you’re choosing before buying. This will make sure that you’re indeed picking something that will work for you.
In case you need a different type of connection like 1-inch or 0.5-inch, look for it. It may take you more time, or more work when installing with adapters – but it’s worth it.
If you want the pump to work at certain times of the day, or for specific periods only, you can set up a timer for that.
Not all models come with a timer, though. And others may come with inconvenient ones. So make sure you pick according to your needs to prevent any issue.
• Flow Rate
The flow rate is indicated in GPM. This is how fast the water can run through the plumbing system using the pump. We don’t have specific recommendations as to what speed you should go for, but we know that the more GPM the pump has the more flow it will have, and the more water it will push.
So, if you can go for pumps that offer between 0 and 10 GPM, it will be enough to work with both low and high-pressure systems. If you want tons of pressure, then go for something of about 15 GPM or more.
• Motor Power
As you know, every pump comes with a motor, so it is essential to understand how powerful that motor is. To do that, make sure you check the amount of horsepower it delivers. We recommend between 1/10 and 1/40 horsepower. Anything less than that will be too little to power normal plumbing systems.
If you want stronger performance, you can go as far as 2 HP of power or even more. But that’s for something like a building that needs tons of potential.
• Temperature Settings
Another practical feature is the temperature capacity of the pump. So, if you want to keep the temperature consistent, the pump may help you do so. It is not an essential thing to have, but it can change your experience with the pump – especially if you want to receive consistent heating at all times.
The less maintenance you need to do to the pump, the better it will be. That’s why we recommend maintenance-free models if you can buy them. They are often more durable and reliable, as well.
If you want a great experience with your pump, make sure it doesn’t make much noise. Some pumps are annoyingly loud, while others can be pretty quiet and relaxing.
If you’re going for a loud pump with tons of power, then we recommend installing it on deep basements. Otherwise, go for a quiet model that you can fit anywhere without the annoyance.
• Ease of Installation
Finally, you should always go for models that are easy to install. Some models even come with all the necessary equipment for the setup. This will ensure that you can get them working almost instantly.
Be careful, though. Some models may be easy to install, but you may still need specific components or tools that you may not have. If that’s the case, then contact an expert to do so for you.
How to Install a Hot Water Recirculating Pump?
After learning almost everything you need to pick the right model, we’ll help you even further by explaining how to install one of these.
You won’t have to be a plumber expert to make this happen. Just follow our instructions, and you can set up a hot water circulation pump at home in a few minutes or hours. Here’s what to do:
1. Start by turning the water heater and the entire plumbing system off. Turn the gas, electric, and water supply if needed.
2. Open up a faucet or sink to drain all the water still in the pipes. Then drain everything on the heater tank. Makes sure there’s nothing left.
3. Now follow the manufacturer’s instructions to install the pump. Remember to use all the equipment like the pipe wrench, plumbing tape, gaskets, supply lines, and anything else necessary.
4. Once you have the pump hooked up with your plumbing system, check that everything is well-connected. Make a thorough inspection.
5. Finish up by opening the water supply, turning the water heater on, and opening sinks and faucets. The water should come out normally. Then close them up and try again – it should go out faster.
If everything goes as explained in this small guide, then you’ve successfully installed the hot water recirculating pump at home.
How to Use a Hot Water Recirculating Pump?
A recirculation pump is an electric machine that makes it easy to push water through large plumbing systems. It maintains the water on the tubes so you can eventually open any faucet or sink and get the hot water without problems. To use them correctly, you will have to learn what they offer.
First, you will get a check valve. This valve makes sure you can either close or open the pump when needed. Without this, you will have a consistent flow of water through the pump that only stops when you close the water supply.
Then, you’ll find a temperature sensor or thermostat. This part often comes with a set function so you can pick the desired temperature, and the pump will help you achieve that on every sink, faucet, shower, etc.
And finally, you get a timer. It is the part that allows you to make it work at specific times of the day. This helps to save water and time, making the machine work manually.
To use a recirculation pump, you will have to open the check valve to let water pass through the pump. Then choose the desired temperature in the thermostat, and finally set up the timer, so it functions only when you need to. Do that, and you’ll start enjoying your hot water recirculating pump in no time.
How to Clean Hot Water Recirculating Pump after Using – Step-by-Step Guide?
If you want to prevent any rust building up on the pump, or any other type of residue from growing inside – then you’ll want to clean the pump every few months. This will ensure that you always get consistent and clean water delivery at home.
Here are a few steps to follow to make this happen:
1. Disconnect the pump from its power source and water line. Then proceed by disassembling it.
2. Pumps have iron, steel, or aluminum covers. Find the screws or bolts to get the cover off so you can disassemble it correctly.
3. Take photos of everything to remember how it is put together. Then start taking out parts one by one without breaking the machine.
4. Once you take them all out, you can start washing them. Use water, dish soap, and steel wool or soft-brittle brush. Get rid of any buildup or residue on the components.
5. Let all the parts dry after cleaning them. Then use a towel to get rid of the excess of humidity if needed.
6. Keep up by putting the pump together again. Follow the photos you took before to prevent any issue.
7. Finish up by placing the cover over everything again, tightening the screws, and that’s it.
8. Try to start the machine before connecting it to any water supply. It should sound and work normally. If it does, then you’re done. Otherwise, disassemble it again to make sure it works correctly.
Do this to ensure that your hot water recirculation pump works clean and consistently for a long time.
How Does Hot Water Recirculating Pump Work?
A recirculating pump is similar to a typical pump like we’ve said before. But the thing that makes a recirculation pump so effective is the ability to be activated at all times. This means that it won’t work only when someone opens the shower or the sink.
The pump starts up and will start pumping water through the pipes. Whether it is cold or hot water, it will go back and forth consistently, so the water is always ready for you to use. Sure enough, when it comes to hot water, this becomes a little more difficult because you’ll need it to be heated.
Moreover, the recirculation system ensures that the water on the pipes is always hot. Here, the hot water recirculation pump will sense the temperature of the water to make sure that it is warm enough for your needs (you will have to set the temperature beforehand).
And if it’s not, then it will recirculate it back to the heater to make sure that it heats up. Once it does, then it will deliver it through the sink, faucet, or shower. That’s how a hot water recirculating pump works.
Frequently Asked Questions
To pick the best hot water recirculation system, you won’t only need to know its features and how it works, but also other less important factors. The following questions may help you out with that:
1. What’s an under-the-sink pump?
An under-the-sink water pump is the machine that doesn’t install close to the water heater or plumbing system, but close to the sink. Specifically, it goes underneath the faucet, so it pushes water fast and effectively. You will need power under the sink to enjoy it.
2. Do hot water recirculation pumps save money?
Yes. This happens because it will prevent your house’s water from being wasted. However, you will need to consider that if a recirculating pump is always working, then it will suck tons of energy, which translates into higher electric bills. To prevent that, only use the pump at specific times of the day.
3. Why is the hot water recirculation pump so expensive?
They are expensive because they need to withstand high temperatures, work consistently, and sometimes sense water temperature, control pressure, and more. This demands high-quality components made of high-end materials, which are highly expensive.
4. Can a sink drain into a sump pump?
Yes, but it demands tons of installation efforts and expertise. If you want your sink to drain into a sump pump, make sure to use the help of a professional.
By now, you should be familiar with everything a recirculating pump offers and how you can pick the right model. But still, it is essential to remember that the right model is the one that best fits your demands and nothing else.
The best hot water recirculating pump will save you tons of money every year, and help you receive fast water delivery at all times. If you need to get one of these, then do it now. You won’t regret it!
