How to drain water from underfloor heating is as follows:
Step 1: Close the main water return valve (pull it into the direction perpendicular to the pipe). ) to prevent leaks in the return pipe. Water is also released.
Step 2: Leave only one side of your home's water dispenser open and the others closed.
Step 3: Connect a water pipe to the return water exhaust valve, unscrew the exhaust valve, and use a small basin to catch the water flowing out of the water pipe.
Step 4: After finishing, repeat the second step, close one pipe that released water, open the other pipe, and so on, until the hot water enters the floor heating pipe.
Steps for deflating underfloor heating
1. Prepare the water pipe and clamps, first find the water discharge position, then find the outletventilation of the water inlet pipe on the water dispenser. Touch it with your hands. The hot one is the water inlet pipe and the cold one is the return pipe.
2. Connect the water pipe to the air release valve of the water inlet pipe of the water dispenser. At this time you must pay attention. There should be someone next to you when the air is released. . Because the deflation hose may burst. Prepare a towel and wrap it around the valve, then use pliers to open the valve. Make sure to do this gently so the water doesn't leak everywhere.
3. Then put the air back into the water line. First, close the main valve of the main water return pipe. The main valve is a long green or red handle. It will automatically close when turned 90 degrees. The method is the same as for the water inlet above, just connect the hose to the discharge valve of air from the water dispenser.
4. Next, install a single water pipe. Operation method: First close the main water return valve. Then close the small valves of the water inlet and return pipe of the geothermal pipe one by one, and then deflate the air relief valve of the return pipe of the water dispenser until hot water sort. Start by closing the small water inlet and return valves of the first pipe, then open the small water inlet and return valves of the second geothermal pipe. Simply deflate the geothermal tubes one by one.
5. Check if deflation is successful. Mainly observe whether there is sewage and gas bursting inside. If so, it will basically reach a stable state.
6. Finally, open the water faucet, including the main return pipe and each pipe. Finally close the purge valve tightly. Underfloor heating and ventilation are termined.
