Installation issue
There is a very small gap between the timer inlet and my faucet Is the specification wrong or is it a defect?
Kindly note there would be a small different for different factories even the same specification. Hence, we sincerely suggest you can wrap some teflon taps on the faucet before installation. For more support, please feel free to contact our customer service team.

We really care about this issue. There may be four reasons for this. Water hammer. To avoid water hammer damage, we sincerely suggest that you install the timer vertically. Vertical installation can greatly reduce water hammer damage. B. Incorrect specifications. Please note that even with the same specifications, different factories will have slight differences. Therefore, we sincerely suggest that you wrap some PTFE tape on the faucet before installation. C. It may fall off the faucet due to excessive water pressure or loose installation. To avoid this situation, you can check whether the connection between the faucet and the timer is tight and whether there is water leakage or looseness. You can also choose a timer that suits your water pressure range, or add a pressure-reducing valve between the faucet and the timer to reduce the water pressure. D. It may be damaged by exposure to sunlight or a cold environment for a long time, causing internal parts to loosen or break, and then fall off. To extend the life of the timer, you can avoid placing the timer in direct sunlight or low-temperature places, or use a waterproof and dustproof protective box to cover the timer. We sincerely suggest that you wrap some PTFE tape on the faucet to make the connection tight. If you need more support, please feel free to contact our customer service team.

If your water faucet is very low and it is unable for you to install the timer, maybe you can try to use a soft hose to install on the faucet before you install the timer.

My value cannot be turn on . No water comes our through the valve. Is it a defect?

We are sorry for the inconvenience.

For the valve might be stuck for some reason/shipping/long storage. Would you please try 5-10 times manual watering to check if it can work well.

Steps for one time manual watering:

2. Press and hold OK button for 3-5 sec enter manual mode;
3. Click OK button to open the valve;
4. few seconds later turn the dial to OFF to turn off the valve.Valve stuck issue can easily solved if you can manual turn it on and off for multiple times. Please have a try.

If not, please contact our customer service team for further support.

Sorry for the bother. Please check if the filter and hose gets stuck by particles. If yes, please clean the filter or exchange it to a new one.

Water leaks from the thread after installatio.

For this issue, first of all, please check if your timer connect to the faucet tightly. Normally, if there is a small gap between the timer and faucet, it is easily to cause leaking issue.

Secondly, please check if the thread is damaged.There is no doubt that damaged thread will cause the leaking issue.

Thirdly, please check if the filter and seal ring is in good condition and in right position. The filter is very important for sealing. If the filter is damaged or missed, it is easily cause leaking issue. If the filter and seal ring are good and in right position, please wrap some teflon taps on the water faucet to check again.

We have reported this issue to our technical and they are testing if there is a new mold helps. I am sure in the no long future, we can figure out this issue.

We are so sorry for bother. It sounds like the inner mold is damaged. This issue happens sometimes during the shipping or the timer was hit. please take some photos to show the issue and send to ling@cosysmartshop.com. Our customer service team will offer further support for it.

For this issue, it might be caused by two seasons.

First of all, it might cause by the valve issue. If the valve get stuck by some reason and do not close in good position. The water will leaks out from the outlet. To solve this issue, please try multiple manual watering to make the valve in good position.
The other reason for outlet leaking might be the connection between the outlet and hose is not tight enough. If there is a small between the outlet and hose, it cause leaking issue too.
