I have never found any one as helpful as john and knows so much about the hot tubs. If you are having trouble with your tub look no further than hottubdiy john will explain in full detail what he thinks the problem is and even rings you as many times it takes you to sort out the problem saving you pounds on expensive call outs from other companies who sends people who have not got a clew and i am speaking from experience .I must say the spares and postal service is second to none,so i can say its hottubdiy for me every time many thanks john.

Air Switch

Got the pump ok but I've opened the box to find it has the air switch, which was optional, and specifically requested one without it. If it won't cause any problems I'll go ahead and use the pump anyway - it just isn't what I'd ordered...
