I need to attach a 35 mm to 22 mm endfeed reducer to a 35mm end of a
35mm x35mm x22 tee.

The problem is that the tee is already fully soldered and installed.

The end that I need to remove has a 35mm to 15mm reducer. I need to
remove this reducer and solder the 35 to 22 reducer.

By applying heat and using pliers I can remove the existing reducer.

Three questions:

1. Will it be ok to clean the inside of the tee with sand paper to
prepare it for soldering or will it be very difficult to get it good
and clean so that I can insert and solder well the new fitting?

2. I know that I risk damaging the other joints in the tee. What can I
do to avoid it?

3. What is the best way to tackle this job?


Thanks,

Antonio

Speed is the best way to go about this job.

Have the new reducer cleaned up, fluxed and ready to insert.
Heat up the old joint and melt the solder.
Withdraw the old reducer and offer up the new one before the joint cools too
much.
Heat the new fitting and the existing fitting together until they are
inserted, now brush on some extra flux around the completed joint and solder
up in the usual way.
