Yes. It was just a case of unbolting the 6 diaphragm housings and replacing the diaphragms. Some had split and were allowing the pump oil to leak out into the spray and spray to mix with the pump oil. The pump oil was creamy as a result. You could replace the valves at the same time but I didn’t bother. They were OK. If the pump is more badly worn than that then I’d enquire about a shop refurbed or new pump. The diaphragms lasted about another 10 years for us but finally then we decided to go far a new pump as it was obsolete and corrosion was lifting the plastic coating off the various parts making it difficult to get water tight reassembly.Did you repair it yourself?
