How to make a brass fitting to copper pipe joint.
Introducing the copper pipe joint made in heaven.
Okay so you have decided to cut in a tee for a dishwasher or maybe your teeing off for another hose tap.
Whatever your plumbing addition is, you'll likely need to make a brass fitting, to copper pipe connection.
Welcome, the one and only Olive or Copper ring jointing system.
1. They are simple to make.
2. Take very little time to do.
3. They need very few tools to perfom.
4. They are strong and durable (just the criteria you need in a plumbing system.)
5. No fire risk as opposed to welding.
Today I'm going to share the some tips to make this connection leak free, every time.
The first tip is you should only use this system is places that are accessible (under floors where building is off the ground or in ceiling spaces)
The reason being, connections in walls have to be welded.
Why?
Pipes are often subjected to slight movement as taps are turned off and on.
Swung on and basically abused.
The olive joint although good, will not tolerate movement and may start weeping as a result of it.
With that out of the way, lets go.
You'll need a
1. wheel cutter (A hack saw and file will do the trick.)
2. Poly/multi grips
3. Adjustable wrench/cresent.
4. Hemp or threadtape. (Hemp is a plant fibre that comes in a roll.
It is used for water proofing joints.
For metal joints this is the ultimate product.) Use thread tape as last resort.
Make the joint.
Now slide on nut followed by olive.Most people including a few plumbers now tighten up the joint and wonder why every now an then, a fitting will leak????
Introducing the hemp grommet.What you need to do is feather out some hemp approx (approx 6"/150mm).Now roll into a very fine length of string. Too thick and it will hinder the nut from doing up.
Hold the pipe in your left hand and roll the hemp grommet under the pipe away from you. (This stops hemp unraveling as you do up the nut. Make sure the grommet is rolled on the pipe end side of olive.Smear graphite over olive and hemp. (This lubricant, makes it easy for the copper pipe joint to do up.)
We're nearly there.All you have to do is slide the pipe into the fitting and tighten nut. Hold fitting with multi/poly grips and turn nut clockwise with adjustable pipe wrench/cresent. If your still with me, you're awesome. Turn the water back on (once you've made the rest of the joints) and let's CELEBRATE!!
