5 Steps Of Boiler Automatic Water Feeder Adjustment

Boiler automatic water feeder adjustment can be a pain. But this article will help you with it.

Here you will get to know how to do 3 types of boiler automatic water feeder adjustments. These adjustments include stopping, increasing, and decreasing the water flow. In addition, you will learn to install a boiler automatic water feeder as well. So let’s start the process.

5 Steps Of Boiler Automatic Water Feeder Adjustment

Adjusting the boiler’s automatic water feeder is very easy. You only have to turn off the boiler system, locate the water supply valve, twist the valve, and restore the system. 

We will be using the manual boiler water feeder adjustment method because it’s easy, effective, and takes a minimum amount of time. Here’s how,

Step 1: Turning Off The Boiler System

Before jumping into the main process, you have to turn off the boiler system first. There are two ways you can turn off your boiler system.

The first thing you can do is use the dial. Turn the dial to the “OFF” position, and the whole boiler should be off.

Another thing you can do is turn off the main switch of the boiler. This never fails to shut your boiler off. Try this manual approach if you don’t want to take any risks.

Step 2: Locating The Water-Supply Valve

Now you will have to find out the water supply valve. This valve is located on the water supply pipe.

Water comes to your boiler from above. So it is normal the water supply line will be on top of the boiler. Once you identify this water line, look for a knob. It will be somewhere along what pipe.

Step 3: Twist The Valve

Once you have found the valve, you have to twist it. Grab the valve tightly and twist it clockwise till it doesn’t rotate anymore. 

However, if you want to slow down the water flow, rotate the valve only a bit. And in case you want to increase the water flow, twist the valve anti-clockwise.

It is very common for boiler automatic water feeder valves not to rotate. This can happen due to a jammed valve. Just use a bit of lubricant at the valve joints, and this should do it for you. 

Step 4: Restore The System

You have adjusted the automatic water feeder of your boiler. But it doesn’t end here. You have to make sure that the water feeder is now adjusted. Restoring the whole boiler system will ensure that. 

Just switch on your boiler’s main switch. Or if you had used the dialer, set it back to “ON”. 

Step 5: Do A Final Checkup

Now comes the moment of truth. See if the boiler is receiving any water. Try to listen for any noise coming from the water feeder line or lookout for any kind of leakage.

If you have adjusted a certain amount of water flow, try to examine if that condition is met.

And with this, your automatic water feeder adjustment is done.

How To Install Automatic Water Feeder For Boiler In 5 Steps

Now that you know how to adjust the automatic water feeder in a boiler, you can prevent leakage or any other damage. Or you can just get the water flow you need.

However, this above-mentioned method will not work if your boiler’s automatic water feeder is broken. If this really is the case, then you have to install a new automatic water feeder.

Here’s how to do it,

Step 1: Get The Perfect Automatic Water Feeder For Your Boiler

There are different types of automatic water feeder devices for different types of boilers. You may need to consult the user manual to find out the ideal one. 

However, a few automatic water feeders have universal compatibility, such as this HydroLever automatic water feeder. You can attach this device to whatever boiler you may have.

Step 2: Disassemble The Water Feeder

Now you can get to work once you have found your water feeder. Start off by unscrewing the bolts holding the bottom panel.

There is only one bolt holding the water feeder box. Twist it anti-clockwise with a screwdriver, and remove the bottom cover. And at this point, the automatic water feeder is exposed to you.

Step 3: Setting Up The Water Feeder

At the bottom side of the water feeder, you will find a pipeline for the water to pass through the system. Tightly install two metal connectors on both sides of this pipe.

Measure the length between the tip of the two newly installed connectors. Now mark this length on the water feeding pipe. This is where your automatic water feeder will go. 

Now it’s time to cut the pipe from the marked point. Take a pipe cutter like this one and do the cutting. After that, you will have a perfect position to place the water feeder. Set it up right here. Make sure to screw it up tightly. 

Step 4: Do The Wiring

It’s time to take care of the wiring. This can be a complicated task so pay close attention. Here your goal is to connect the red wire of the automatic water feeder to the water supply system.

Firstly, cut an opening in the red wire of the water feeder and in the water supply system wire as well. Take a long wire. It should be long enough to secure the connection between the two panels.

Now cut openings on both sides of the long wire and connect one end to the water feeder wire. The other end will go to the water supply systems wire. Use duct tape to secure the wire connection.

Step 5: Wrapping Up

Now you are done. You have successfully installed an automatic water feeder in your boiler. But there are a few things left to do.

Firstly, put the cover back on the feeder. Screw it there just like you unscrewed it at the very beginning. And then turn the boiler system on. See if there is any leakage or anything.

If you notice any problem with your boiler and find it doesn’t start, call an expert to look into this matter.

And with this, you are all set.
