# Indoor water leakage

[**Indoor water leakage**](https://www.renkeer.com/water-leak-detection/) is a common problem that can be caused by a variety of reasons. Here are some common causes of indoor water leakage and their solutions:

Indoor unit is not installed firmly

Cause: The indoor unit fixing plate is not installed firmly, which will shift over time and cause water leakage.

Solution: Check and reinforce the fixing plate of the indoor unit to ensure that it is installed firmly.

Improper horizontal installation of the indoor unit

Cause: The indoor unit is installed tilted in the horizontal position, and the position of the pipe outlet is too high, causing the condensation water to be blocked.

Solution: Adjust the horizontal position of the indoor unit to ensure that it is installed flat so that the condensation water can be discharged smoothly.

Bad drain pipe

Cause: The drain pipe is aged, blocked or improperly installed, resulting in the inability to discharge condensation water.

Solution: Check whether the drain pipe is aged or blocked. If necessary, replace the new drain pipe or clean the blockage. Make sure the drain pipe is installed correctly and there are no gaps.

Dirty filter

Reason: The filter is seriously dirty and has not been cleaned in time, resulting in the condensation water formed by the evaporator during air conditioning cooling not being able to drip into the water tank in time, but falling outside the water tank, and the water droplets will slowly leak from the bottom shell into the room.

Solution: Clean the filter of the air conditioner regularly to keep it clean.

Insufficient refrigerant in the air conditioning system

Reason: Insufficient refrigerant in the air conditioning system causes the evaporator of the indoor unit to freeze, resulting in the condensation water being unable to be discharged normally.

Solution: Contact a professional air conditioning maintenance personnel to check and replenish the refrigerant.

Damaged pipes

Reason: The pipes in the house are broken or damaged, and water flows out through the cracks.

Solution: Find the leak point and carry out targeted repairs. If the pipe is seriously aged, consider replacing a new pipe.

Damaged waterproof layer

Reason: The waterproof layer is improperly constructed or damaged after long-term use, resulting in water penetration.

Solution: Shovel off the damaged waterproof layer, re-waterproof it, and conduct a water seepage test to ensure no leakage.

Water seepage in the corner

Reason: The waterproof coating in the corner is not well done, or inappropriate waterproof materials are used.

Solution: Re-waterproof and choose suitable waterproof materials, especially flexible waterproof coatings, to ensure that the coating can better penetrate into the cracks.

Ground subsidence

Cause: The ground subsides, resulting in cracks near the corners.

Solution: Check the ground subsidence, repair the ground if necessary, and re-waterproof.

Water leakage upstairs

Cause: There is a large area of overflow in the bathroom or other floors of the upstairs residents, and the waterproof layer is damaged, resulting in water leakage downstairs.

Solution: Communicate with the upstairs neighbors to jointly find the leaking point and repair it. If the other party does not cooperate, you can complain to the property or other relevant departments.

Air conditioning drain pipe is blocked

Cause: The drain pipe leading to the outside is blocked artificially or the drain outlet is blocked by stolen goods, resulting in condensation water cannot be discharged.

Solution: Clean the blockage of the drain pipe to ensure smooth drainage.

Water pipe interface problem

Cause: Cracks or corrosion appear at the water pipe interface, resulting in water seepage.

Solution: Replace the water pipe or wrap the interface with tape several times again to ensure a good seal.

Problems with the connection of the sink drain pipe

Reason: The sink drain pipe is not seamlessly connected to the main drain pipe, causing water to seep out of the cracks.

Solution: Check and reconnect the drain pipe to ensure that the connection is well sealed.

Problems with the faucet angle valve

Reason: There is a problem with the faucet angle valve, causing water seepage.

Solution: Replace the faucet or wrap the angle valve with tape several times to ensure a good seal.

Problems with decoration construction

Reason: The waterproof layer is damaged due to changes in the house layout or drilling holes during the decoration process.

Solution: Re-waterproofing to ensure that the waterproof layer is intact.

The above are some common causes of indoor water leakage and their solutions. If you encounter a complex water leakage problem, it is recommended to contact a professional maintenance personnel for inspection and repair.
