Cimex solution tank problem

[Lounge Lizards]

With the later model solution tank, Houston, I have a problem.

The brass valve that is inserted into the base of the tank, becomes very thin over time.

This then starts to leak as it is cracking finely.

When trying to undue the Shut-off valve, the brass piece finally broke.

I then had to replace the shut-off valve also, as the brass threads were jammed inside.

I was able to squeeze the brass down with my fingers, that’s how thin it got.

LUCKILY, I had a spare tank as it’s IMPOSSIBLE to remove the threaded brass from inside the solution tank.

Glued into the base of the tank is a hex; nut.

The brass “valve”, which is basically a hollow brass pipe which is threaded on the exterior.

This screws into the hex; nut & appears to have been glued in with some substance.

Trying to remove the “valve” will result in more crushing of said “valve”, thereby making a complete tank replacement necessary.

There are then two more hex; nuts screwed onto onto this before it is screwed into the shut-off valve.

I never had this problem with my originCimex tank, only the Trevox  tank.

Any solution??
