^ whats the machine in the pic mick ?
anywhere they advertise a 220psi pump , its the aquatec diaphragm pump , the one i got with the alltec express has a demand switch ... but also a small regulator .
since then the demand switch burned up ... as they do .... so i just bypassed it ... and then with some more fooling around i removed the regulator .... so no it just runs full and continuous ... which its happy to do as its an internal bypass .
just to confuse things the 220 pump now has 250 on it ( slightly newer perhaps ) ...on woodbridges site
