Let´s go to work
Step 1: Materials
*- A water meter (of course!) in mi case a 3/4 new generation polymer home water meter.
*- 1st step water filter (this can be removed) but i considered usefull.
*- 2 3/4 galvanized union nut. (it can be copper but it´s more expensive)
*- 2 3/4 copper elbows.
*- 1 3/4 copper elbow with rope.
*- 4 3/4 copper weldable coupling. If you removed water filter only use 2.
*- 3/4 copper tuber. The quantity that you need.
*- Teflon tape.
*- Anti-seize can
*- Blowtorch, welding and solder paste.
Step 2: Preparing the parts
Joint approximately a half of the thread.
Step 3: Examining and measuring
I sprayed a bit of anti-seize in all the junctions. DONT FORGET CLOSE THE STOPCOCK.
After that i used parrot key and stilson wrench to remove all the tubes that i don´t need.
I proceeded to weld the elbows, coupling and put it togheter with the water meter.
You need to bee very carefully in this step becasue you need to consider the order placement.
First i put the copper elbow with rope then weld the copper tube, the elbows and the coupling.
Joint the water meter to the coupling using the union nut. In the other side the union nut to the coupling and the elbow.
Ending with the union between the two cooper coupling.
