Leakage problems are usually solved by tightening or replacing pipe joints. However, excessive tightening will wear the metal joints and plastic joints. If the leakage problem cannot be solved by slightly tightening the joint, the joint must be removed and rechecked the damage (for example, damaged sleeve, impurities on the sealing surface). The broken joint should be replaced.

**Problem: Leakage**
Problem	Solution
1. Leakage at the joint.	Generally, tightening, cleaning, replacement, and other methods can be solved.
2. Pump leakage.	Check whether the check valve, the joint is loose, if loose tighten (not too tight). Check whether the seal of the mixer and pump is damaged.
3. Leakage of the injection valve.	Check whether the rotor and sealing port of the injection valve are loose. If so, tighten them. Check whether the waste liquid pipe is blocked or siphons, dredge or replace the waste liquid pipe, and keep the waste liquid pipe higher than the waste liquid level.
4. Leakage of the column.	Tail joint loose, tighten the joint; There is packing in the card sleeve, remove the card sleeve, clean the card sleeve, and reinstall; The screen plate thickness is not suitable, replace the suitable screen plate.
5. Detector leaks.	Check whether the gasket and window of the circulation pool are damaged, and replace the gasket or window. Check whether the flow pool is blocked, replaced, or reinstalled. Check whether the waste liquid pipe is blocked and replace the waste liquid pipe.
