Noisy condensate on Worcester Greenstar 25i

[ESB]

Boiler installed 7 weeks ago. Every 2 or 3 days I hear the condensate water running down the pipe loudly and then a glooping noise from inside boiler for approx 30 seconds. Boiler operates well. No error messages or flashing blue light. Any ideas what could be the cause? There are no blockages. Condensate pipe run into sink waste which washing machine pipe is also connected to.

That's normal washing machine pipe untrapped ?

 

[ESB]

Many thanks for coming back to me. How do you mean untrapped?

 

[ShaunCorbs]

Does the washing machine waste pipe go in the kitchen sink or to its own stand pipe ?

 

[ESB]

See pic if this helps. You can see the condensate pipe to the right. The glooping is really loud as is the sound of the condensate water running through before the glooping. I phoned Worcester but they can't attend until January! They didn't think it should make that noise but they have not heard it

All looks fine how does the kitchen sink drain ?

 

[ESB]

Kitchen sink drains well. I put 2 lots of drain cleaner in to be on safe side. It drains fine. No bubbling or gurgling. The sink gurgles a bit when washing machine on.

Seems like there could be air in boiler after draining condensate? Odd it only happens every few days. Maybe not dumping condensate enough? Had a new kitchen tap fitted a couple of weeks ago but that shouldn't make any difference. Worcester mentioned getting a tundish fitted...

 

[ShaunCorbs]

Why was the condy drained ??

Not normally

 

[ESB]

Condensate drained? Sorry. I am being a bit thick here!

Condensate drained? Sorry. I am being a bit thick here!

You said it was drained in the above comment or do you mean emptying?

 

[ESB]

Emptying. Sorry Shaun

 

[ShaunCorbs]

Emptying. Sorry Shaun

Np I would say it's running fine and it's supposed to

If you not running the hot water much and heating on tick over it's about right emptying around a day

Thanks Shaun. I only hear it once every few days. I have the glooping on video but can't upload it here as .mp4 file type not allowed! The glooping is really loud! Have you come across this before?

 

[ESB]

There are only 2 of us here and hot water not run much as you say.

Thanks for your replies. Am in contact with installer. Will let you know how it goes

Installer came out and recreated noise by running hot tap until condensate emptied and said he thinks it is operating as it should and it is the noise of the condensate emptying. To stop the noise of the condensate going down the pipe I could have a bigger pipe but the noise doesn't bother me as long as I know it is normal.
