Post #33 has all you need. I have done this a few weeks back and I wish I had done this 16 years ago.

Hasn't seen over 188 yet.

 

I am sorry. I still don't see a big value going through all the mods and shell out almost $150 bucks

 

A copper T-fitting has worked really well for me. I have a thick rubber washer on the bolt head on the inside. I did thread the copper hole for what it was worth. Notched the end of the bolt so I could keep it from rotating when tightening the butterfly nut. Flared the ends out so the hose wouldn't be able to pop off under pressure.

 

I see this is the most cost effective way. where did you get the copper T ? size and part number?

I am also impressed by this design someone did but not sure what they used for 3 extensions.

 

did they use this and cut off the Thread at the pipe end?

 

Standard copper T from Home Depot. I just took the old plastic part with me to match size. Wandered around till I found all the parts I needed. The hardest thing was flaring the ends of the T. I think I used a socket that was a little bigger and a rubber mallet.

 

Actually while at Home Depot, I went to the tools section and grab a ball peen hammer and insert it on the end and hammer it while youre there. Thats what I did and all the ends got the flaring.
You can also get the brass needle valve LFA-41 drill and tap it on the top of the Tee. Then solder.

 

There are custom stainless steel T pieces available with a S/S bleed screw which are online either in the UK or europe. Personally I don't like using galvanised or iron pipe fittings over other materials but that is just me being subjectively picky.
