What should I do if the wall-hung boiler does not drain after changing water?

If the wall-hung boiler does not drain water after changing water, it may cause the dirt, sediment and waste in the boiler to mix into new water, which will affect the operation and service life of the equipment. Therefore, when replacing the water in the wall-hung boiler, we must pay attention to the drainage operation. The following is the solution to this problem:

1. Find the drain valve and open it.

There will be a drain valve under or on the side of the wall-hung boiler. Generally, there is a slogan "Drainage" on the valve. After finding the drain valve, you can loosen the valve with a wrench or wrench, and then pull the valve outward. In this way, water will flow out of the wall-hung boiler.

2. Collect the discharged sewage.

When the drain valve is opened, dirty water will flow out from the drain, so it is necessary to prepare a container to receive the discharged wastewater.

Step 3 drain the water completely

Be sure to wait until all the dirty water in the wall-hung boiler is drained, and do not leave any sewage or sludge.

4. Close the drain valve.

After drainage is completed, close the drain valve. At this time, you can change the water and carry out the corresponding operation according to the provisions in the manual. Check whether the drainage is normal after changing the water and before starting the machine to see if there is abnormal sound or water leakage.

In short, we must pay attention to the drainage operation when changing the water in the wall-hung boiler. If there is no drainage, we must find the reason and solve it. In order to ensure the normal operation of the wall-hung boiler, regular blowdown and cleaning operations can be carried out, which can avoid problems such as pipeline blockage.
