OK, I'm getting a little frustrated and I'm not sure what to do.
I've been waiting close to a month for the plumber to get the right fittings for my machine, but this is getting nuts. I could fly to the UK, get what I want and fly back in less time than this.
I lost my patience and went to a plumbing supply warehouse where I described what I was trying to do. I picked up the following fittings: 3/8" NPT Female to 1/2" NPT Male 90-degree x 1 .. (Connects to underside of espresso machine) 1/2" NPT Male to 3/8" NPT Female x 2 ... (Each one connects to each valve on the canister water softener) Dishwasher Supply Hose x 2
Just as I thought, Nothing quite fits. The diameter is correct, the thread count is wrong. Even with three layers of Teflon tape on the threads, two turns and they go in but they still leak slowly. Thought I'd try it but this confirms that everything, the espresso machine and the canister water softener are all using BSP threads.
Where on Earth can I find the right adapter fittings to go from NPT to BSP thread? (Any Recommended suppliers in Canada I can use?)
Here's what I need:
Male 1/2" NPT to Female 3/8" BSP x 2 90 degree Female 3/8" BSP to Male 1/2" NPT
I have no idea even where to get hoses, so I figured that at least I could use "Dishwasher" style hoses since everyone seems to sell them. They're 1/2" NPT female on each end and steel braided. I thought it was worth at least a try because the hoses were the expensive parts, the fittings weren't that expensive, probably less than $10 for everything.
Garbage In, Garbage Out, for every step of the process. From Beans to grinder, grounds to machine, coffee to cup.

You should be able to only convert once. If your softener is american, use NPT hoses to it and convert once going to the machone. If the softener is euro, convert between the plumbing and the softener and stay BSP between it and the machine. Your plumber is trying to nickel and dime you on brass fittings. Convert once if you need to. Converting more than once is obviously... Well, would you exchange your money to euros and then convert those to american dollars when going to the US? You can get one hose with female NPT on one end for your american shut off valve at your wall, and a female BSP to go to your softener (Assuming it too is euro), then stay BSP because the machine is euro, also. I will see what my guys have in the vans, tomorrow, and I'll post again. Hang tight.

You could also go from BSP to tube (barb fitting) and match the tube. Just make sure you have tubing that is rated for 60psi or more. (These would be reinforced, most non-reinforced would only be good to maybe 20psi depending on the diameter.)
You can go to McMaster-Carr website, the're in New Jersey so I don't know about shipping to Canada. The would have most everything you need to do it yourself. They have some BSP to NPT but not very extensive. I'm not sure about your connection to a dishwasher supply hose, I'm not sure it is NPT?
I'm in the process of plumbing mine up so I was going through the fittings last week. Although I went from an old washing machine supply (GHT) to NPT (Filter) to BSP (Machine).

Qualin, Whereabouts in Canada are you? Nuova Ricambi carries the adapter fittings as does Ascaso factory. Astra M Group is an authorized dealer for both of those manufacturers. They are located in Mississauga near Toronto. I have received outstanding service from them. Ask for Krassy and tell her Dave from Latte 911 sent you. You will not be disappointed. Best of luck.
BTW: Nuova Ricambi part numbers for the following items:
3/8 compression to 3/8BSP or Italian: 300055 3/8 Flare to 3/8BSP or Italian: 300056
Less than $10 each. PM me for the website link and phone number.
