Mine has become very slow. When i switch my pole valve off and then re-open again for the next window i have to wait for the varistream to kick in and start the pump up. Any ideas? Maybe the cold weather? Stiff pipes?

Maybe bad connection, I had a problem this week so cut off old connections and stripped back new ones. You will find the connections tend to go black restricting the voltage flow.

Could not believe the difference when I did it, had to turn the varistream right down.

Hi Dave,similar situation here mate,i have heard that very cold water is thicker so probably will run slower,i did notice while the water was running down the windows it looked thick and ran down slower so may be just maybe mate

Bin the connecters that come with the varistream and replace them with bullett ones,far better connection.
