Duncan came round to investigate why my pump wasn't working on a public holiday, found the issue, fixed it, replaced some old fittings, and all the while - at my request - explained exactly what he was doing and why so I could learn how it all works. And all for a very reasonable fee! 5 stars Thanks so much!
