  If there's no water flowing from your iflo Plumbing Product, several issues could be the cause. First, check if the water isolating valve is in the off position and turn it on. Also, the filter or the outlet hose mesh filter might be blocked. To resolve this, turn off the water supply, then remove and clean the filter or remove the outlet hose from the shower, remove the mesh filter and clean it. Finally, ensure the power supply to the unit is switched on.

  If the water temperature from your iflo Plumbing Product is too hot, it could be due to insufficient water flowing through the shower. Try cleaning the handset to improve water flow. You can also increase the flow by adjusting the temperature control knob to a cooler setting and reduce the power setting.
