SOLVED!!! Fed up with cold showers using my Aqua Jet pump I decided to have a go a fixing it myself. After all, if I sent the old one away I'd be without a pump so I'd have to buy a new one anyway. Just under a little paper sticker at the pointy end of the pump (I think it said something like 20psi) is an Allen screw which adjusts the pressure. About 2 clockwise turns on this with an Allen key and the problem is solved!! Great pressure and more than enough to run my boiler constantly and have lashings of hot water! If you decided to try this it will almost certanly invalidate your warranty (they'd probably try and wriggle out of it anyway) but it worked a treat for me and saved me about £50 on Ebay for a new pump.

Hi - I have exactly the same problem with my Johnson Aqua Jet pump. It was fine when I first fitted it but now it cycles on and off so slowly that my boiler only just kicks in before the lack of pressure turns if off again. My showers are luke warm at best and no fun during these freezing November mornings! Going to check my local chandlers for a separate pressure switch or failing that buy another Jabsco. Much better quality.

I used PVA glue to stick my small glass mosaic tiles and then standard grout. They've not moved or come loose in a year - but being glass they're easily broken when I drop the fire poker!!
