My flat has g.c.h with water tanks immediately above h/w cyl. Because o
the clowns who designed it I only have 4" clearance between top o water tank & top of inspection hatch so I cannot work inside the tank However I have better access on the o/side where inlet feed pipe enter tank. This pipe is15mm (all sizes o.d.) & has a nut/union ,25mm leading to a short threaded pipe,21mm. ,which has a flat nut,35mm, a the end where the pipe goes into the plastic tank. If I undo this lo will the the b/c*ck & valve come off so I can replace them? Thank yo
