I had great service from the knowledgeable staff, followed up with quick (and free) delivery. On fitting the valve, I had a problem and there was no hesitation in taking back the valve to test it. Even though it turned out not to be the supplied valve, the staff were still very helpful and keen to help me resolve things. I'll definitely buy from Solenoid Valves/Connexion Developments again. Thx and Regards M Clifford
