Every now and then, small faults occur in the HVAC systems in your home, which can be easily fixed with a DIY solution. We’ve put together three common problems that you can solve yourself.
1. Leaky padlock
Often, a leaky diffusion lock is caused by incorrect installation. The sink may have previously drawn badly, resulting in a diffuser lock being removed, cleaned and reinstalled incorrectly. If this is the case, it can be easily fixed with a simple screwdriver. Remove the diffusion lock and make sure that no part is out of alignment. Also check that the seal is facing the right way. If you experience difficulties or if the leak persists despite correct installation, contact a professional. If the diffusion lock is again clearly in poor condition or old, it should be replaced with a new one.
2. Expression of radiators
Old radiators in particular may have cold spots. This may be because air has got into the radiators. In this case, the radiators must be vented, i.e. the air inside them must be removed. At the end of the radiators is an air screw. Carefully turn the screw counter-clockwise with the air wrench – this allows air to escape from the radiator. Keep turning the screw until water starts to leak from the radiator instead of air. Turn the screw back on and dry the leaked water, for example with a rag. You can also put a container under the screw, into which the water will drain during the operation. If you have to air your radiators frequently, you should have the heating network condition survey, which is offered free of charge by HVAC Security for detached houses.
3. Cleaning the floor drain
When a floor drain is not draining properly, it is worth cleaning it at the latest. Open the well and remove the padlock. Remove hair and debris from the well. In addition to this, the inside of the well should also be washed with chlorite using a dish brush. After cleaning, rinse the floor drain with cold water. Under no circumstances should you use the same brush for washing dishes. We recommend that you wear rubber gloves throughout the procedure.
When the finger goes in the mouth
If you are not sure what you are doing, it is often wise to contact a professional. After all, mistakes in HVAC can be costly. Often, the equipment needed to solve problems is equipment that only professionals have. One example of this is a sewer camera, which can be used to check the condition of the sewer. A regular inspection of the condition of the sewer should be carried out, especially if the pipework is cast iron. Fortunately, it’s particularly easy to find out the condition of your drains with a free drain survey from Plumbing Security.
