If you can get a similar look I wont be nasty to you, though I suspect you may already look not too different!!!
The Farrow System had a knackered diaphragm in the water pump, split in two places. We had also taken a non return valve off the tank because it was leaking, when we first used it, not thinking that it was relevant.
It turns out the non return stopped media going through the pipework, that is 1/8 inch, so got clogged up.
I was sold some glass media as well that was course and it was too heavy, this is what we ended forcing through all the pipework.
Had a nightmare trying to find someone to resolve the issues.
There is only one person i'm aware of that knows Farrow systems, phoned loads of people up in blasting to repair but nobody could.
Met up with a guy called Tom in Hull, bit of trial & error and he sorted it at very reasonable rates, just a long old day getting to Hull and back.
I probably know as much about the system and repairing it as he does now.
Got some spares for just in case and have a tonne of coarse glass for sale - you could use it for diamantes when you try to impersonate Boom Boom for me!!!!
