The water flow is too small, and domestic water becomes a problem. The water pressure is unstable and the floor is too high. The bath water is cold and hot, and the water is weak and intermittent. How to Use: First, you can directly connect the pipeline with the booster pump. At this time, the thread specification is NPT3/4, and the pipeline corresponding to the female thread can be connected. Install the water flow switch and the pure copper joint kit, the thread specification after installation is NPT1/2, and connect the corresponding female threaded pipe. Plug in the power supply and switch to manual or automatic. Manual mode means that you do not need to install the water flow switch and pure copper connector kit, but need to manually control the water flow switch; the automatic mode is to install the water flow switch and pure copper connector kit, you can automatically control the on and off of the water flow through the water flow switch.
