They are the ones that didn't last the sureflow original s are good but im temted with the ones from gardiner s
Thanks for that. Although my original shurflo that must be getting on to 10 years is still going strong, except for an unknown hiccup last week where it appeared to get power but not turn, but once removing it to check it properly sprang back in to life.
Think I'm going to put the new pentair spare on instead just incase it doesn't last whilst under warranty.
