    Sounds like DE. The pump wants to pump but you are not letting it by having the flow off while the power is on.

    Rudders is dead right. I don't use a pressure switch just a tap on my hose. When I turn water off it makes a working sound. Perfectly natural. Not all backpacks have pressure switches. Check before you buy it. It a say 2 speed or 1 speed or flow rate switch

    Sounds like the pump is running on slightly after the flow is stopped. It is fairly normal for a pump to run on for a few seconds once the flow has been shut off at the pole. However if it is more than this, then please feel free to email me a short video showing the noise as the flow is stopped. If you email this to me on my personal email address of alex@agardiner.co.uk I can take a look/listen and let you know what it may be.

    You can count on one hand how many bosses of a company take time out to help customers with there problems. I have nothing but praise for Gardiners. There staff are always extremely helpful and orders are very quick to arrive.
