The pump is delaying in activation? What could be the cause of this?

If the pump is slow to switch on it could be because there is something restricting the flow of water.  This could be:

• Blocked filters – these are found on the inlets to the shower pump. Click here to find out how to clean them.
• Shower head is partially blocked with limescale.
• Twisted hose to the shower head.
• Possibly the wrong pump has been installed e.g. you have a positive head pump but there is not enough natural flow so you need a negative head (universal pump). Watch the video to find out the difference between positive head and negative head.
