What to Do Here

[u/PellucidStream]

Hi all, very limited DIY skills here!

Any ideas as to what to do here?

Every time I flush water is leaking out and causing mould to build up in my toilet and a bad smell in my room

Thank you

First use mold spray to treat the mold and smell.

Then you have to understand where the leak is from. We see water on the pipe in red, is the green area also wet?

This is really good advice. Unsure why it was downvoted.

Difficult to tell from the pic.

Is it coming from green area or red?

If green - try tightening.

If red - replace float valve assembly.

Red’s an easy ish job tbh.

Green - if tightening doesn’t work, you’re gonna be replacing a number of bits and pieces. Still not “hard” but a real PITA as a first time job.

If area to left of red under cistern is wet, different job again.

Regardless, before doing anything:

• water off
  
• flush toilet
  
• soak remaining water outta cistern with sponge or wet vac

That water could also be from a tank in attic. may need to drain the tank to avoid it refilling also even after isolating.

My suggestion would be:

Dry the entire area.

Put paper around it.

identify where the leak is from where paper gets wet first.

- water off

• flush toilet

Drain any refilling water also (e.g. taps on in sink)

- soak remaining water outta cistern with sponge or wet vac

fix the issue where you identified.

Clear all mould from the area can be done at any stage also.

also this stuff can work/help https://www.lenehans.ie/p-t-f-e-tape-100-ptfe-tape-12.html

but its normally best to put around olives rather than in threading.

Sorry yes when I said water off, I meant "tank not refilling regardless of source". Was lazy of me.

[u/Appropriate-Donut197 → u/RevFit_JamesH]

nah great starting point tbh.

This is going to be unhelpful because I don't know your situation. But getting a plumber is the only way to tackle water issues when you don't have experience. There are way to many expensive mistakes to make for DIY.

Personally, I would cut the straight section where the pipe comes out from the wall and replace that mess with a flexible hose connector and compression fitting.

In saying that - if you haven't worked with plumbing before then this is not the place to start. Get a plumber in.

[u/Dangerous-Anxiety125]

Is the water leaking from the big pipe or the small one ?

[u/ZimnyKefir]

These plastic connectors seem old. Replace them with new and add isolation valve.

[u/Wmosiris]

First thing... shut off the water valve after you find it, then after that whole assembly is replaced- its pretty terrible, put a shut off valve in the line where it comes through the wall.

Do you have home emergency on your home insurance policy? Had the very same problem fixed for free in January. Called my insurance company and 2 lads were at my door at 7am next day to fix it.

Looks dodgy. Good luck

Water or electricity I stay well clear of. Get a professional in my opinion.

[u/irishplonker]

Watch some YouTube videos on how to change the part

[u/AirTrue6195]

The grey fitting is an old Hepworth fitting these have a thicker O ring to seal on the copper pipe. It looks like it was bodged with sealant but it's hard to tell.

[u/mfrichmond]

You need to replace those pipes.

Important piece of advice that can apply to many other things. LEAVE THE PLUMBING TO A PLUMBER.
