Pump upgrades

I've been using a Totton GP 20/12 for my last few brew days. This pump came as standard with 15mm smooth ports, which take push on fittings. I haven't been too happy with the degree of movement the push fit fittings allow, they also swivel, which can make operating a ball valve on the outlet a bit tricky. I rang Totton who advised that they do a threaded pump head with 3/8th ports. Not ideal as most of my fittings are 1/2", but I happened to have 2 x 1/2" to 3/8" reducing bushes, so that was that, problem solved.
