As we can’t see what work is required from our computer screens I would advise you to hire the services of a suitably qualified Plumber from your area to come and have a look with the view to giving you some advice and a quotation to undertake the work for you.
A small fee to a professional now will save you a lot of heartbreak and cussing if you try and do the work yourself and things go wrong.
Knowledge is what we have and for a small fee we are usually willing to part with a little of it to our customers.
What have you got to loose?
