Just put brand new hose on but the water don't seem to come out as fast as my 8mm hose. These ThermoboreBore are only 6mm and I find the flow slower, also my pump don't sound right with the thermo. Every time I adjust the gas and water flow the bloody gas goes out on the hot wash. I don't have my water that hot really only to keep the hoses soft from freezing. I'm sticking to my 8mm hose don't have no probs with the flow and heater so anyone wanna buy the thermo for £35, I'm in Essex if you wanna pick up or I may be in your area as I go to Cambridge, east south, north London, Felixstowe let me know
Cheers
