I have a swimming pool, and recently the control lever on the 6-way valve was becoming more and more difficult to turn. So I went to my pool records and found an article by your Jolly John, on page 87, of your Costa News, dated December 18-24, 2015, and found the instructions of how to deal with said lever. Perfect instructions. Job done. So even though Jolly John has left us, his advice still stands.
