In fact, it does not waste a lot of water. If the water level of the fish tank is higher than the water level of the water outlet, you can turn off the faucet, and the siphon will automatically draw the water out.
If you want to drain quickly or if the water level at the outlet is higher than the fish tank level, please keep the faucet open.
If you feel that the draining speed is very slow, you need to turn on the faucet completely
If the sand washing pipe does not work well, please turn on the faucet and increase the water flow speed, so that the gravel cleaning function will perform better.
Please make sure that the water pipe can be folded or bent. If the water pipe is bent more than 30°, the water flow speed will be greatly affected. Please keep the water pipe unblocked.
