My flow control was a little hit and miss yesterday kept cutting out when it shouldnt of been, then it stopped altogether.
The fuse looks fine so do i just order a new one? It was just a cheap one off ebay £45 lasted 1 year or so.
Battery is filly charged and pump works fine when i just run it without flow control.

Any ideas.

Hmm it could be that the unit has shorted and blown. But may be worth switching the fuse particularly if there is any corrosion on the fuse or fuse holder.
The fact it was cutting in and out suggest a current issue hence the suggestion to check the fuse also check the cables and connectors that run between the pump - control - pump look for any loose connections or damaged cable.

If its none of those the unit has shorted out and will need replacing.

Don't use a flow control as the pump has its own flow switch which stops when water is shut off so no build up and have ben like this for 6 years without a flow controller, but you could try using a dimmer switch unit to slow the flow.

I will give it to my electrition mate to have a look at, tomorrow i am running the pumo without a flow control! My battery will take a beating i guess ha

Two of us work with two pumps from one battery.  It does 600 litres no problem.  I charge it every day though; well to be honest we use two batteries, while one's charging, we use the other, then I swap them at the end of each day.

One of these batteries is over two-years old.

Your pump is capable of drawing 9 amps an hour running flat out. so you will see the battery voltage fall away quicker than usual.

Most battery manufacturers recommend a battery is not drained below 10.5 volts on a regular basis.
