Help with toilet

[mcdommo]

Hi can someone help I fitted a new syphon to my close coupled toilet and coupling kit and followed instructions to the letter but have a leak coming down one of the bolts which have a wing nut any suggestions would be great

Did you fit a new rubber doughnut on the plastic nut under the cistern?
The old one sets and shouldn't be reused.

 

[mcdommo]

Yes brought a new coupling kit

 

[mcdommo]

Could it be leaking between the cistern and the metal plate ?

 

[petertheplumber12]

Then the only answer is take it apart examine for causes of leak and refit, you may need to use some silicon sealer although I try not to since it make subsequent dismantling difficult.

 

[mcdommo]

Where would you recommend to put the sealer ie between cistern and plate

 

[seco services]

Is it a constant leak or only when flushed ?

 

[mcdommo]

It's constant ?

 

[seco services]

More likely leaking from the seal on the syphon when you put it in the cistern
is the plastic nut on bottom nice & tight ?

 

[mcdommo]

It's not loose but I didn't do it up to tight probably about half turn after hand tight

 

[seco services]

As said start again and use abit of clear silicone on the seal.
Poss the bottom inside is not quite even and the seal not taking that up, or at worst an airline crack in the bottom when you have tightened it.

Take the cistern off and stand it somewhere and fill it with water and see where it leaks.

 

[mcdommo]

I'll give it ago Tom and see what happens is it best to let silicone dry before refilling

 

[seco services]

Yes
