Sink Gurgling Due To New Washer/Dryer

[bainsteven]

Hiya Guys,

New here - just needing a bit of advice, please!

We've just replaced our old washing machine with a washer/dryer (LG F14A8YD6). Now every time the drum stops rotating we're getting a gurgling sound coming from the sink.

The only differenced in the plumbing (as far as I can tell) is that the new washer/dryer doesn't have a hot-water connection (whereas the old washer had both a hot and cold pipe). Could this be causing an issue?

I was also wondering if the waste pipe hasn't been installed correctly? - although, again, I can't see any difference from how the old one was installed... it comes over the back-board under the sink and then down into the sink's waste pipe. Is there supposed to be a U-bend/upside-down U-bend above/below the the height of the washer outlet/sink waste pipe?

Any advice as to why our sink has now started gurgling would be very much appreciated! I've Googled the issue and everyone seems to be suggesting installing a vent(?) - however our old washer was set-up (almost) the same, so I can't see this being the issue?

Cheers,

Steve.

Was the last machine also a condensing dryer?
It's probably the drain pump starting / stopping at the end of each rotation in drying cycle.

Hiya Snowhead- thanks for your reply!

No, the old one was just a washing machine... I'm not sure now if the gurgling only started happening during drying... if so, what can be done about it?

Cheers,

Steve.

Is the new hose longer? Just a guess but if it is laying on the floor could there be an air syphon effect on the waste trap hence the gurgling?

Hiya rpm,

Not sure - I'll check with my Father-in-Law who connected it to see if he remembers (before I pull it all out and have a look!). It's not touching the floor under the sink - but I guess there's a possibility of it being on the floor behind the machine (although my Wife doesn't think it was THAT long).

Snowhead: The gurgling also happens during a 30min normal wash cycle (just trying it now and it's still happening) - so isn't solely due to the dryer pump.

Can you put the plug in the sink, see if that makes a difference, gurgling is water displacing air in pipe or a syphon effect normally. Does the sink drain well on it`s own?

Built in on new hose you thinking?

 

[stevetheplumber]

hose should rise from machine to just below work tops and then run down to the trap

Therefore giving the discharge pump an easy life.

There will only be one drain pump, used for both the dryer and washer cycles.

If the washer / drier drain is connected directly to the sink waste, you'll need to change to having a normal waste riser with it's own trap connected below the sink trap.

Snowhead: While I was washing-up I put plugs in both sinks (we have a middle small sink too) - this stopped the gurgling, and by removing the middle sink's plug the gurgling happened again... so what does this mean? After washing-up the full main sink seemed to drain well as normal.

If the washer / drier drain is connected directly to the sink waste, you'll need to change to having a normal waste riser with it's own trap connected below the sink trap.

What does this mean exactly?... I know nothing about plumbing! Lol.

Hammers4Spanner: What's a "hepvo"?

SteveThePlumber/rpm: I believe this is how it currently is: The waste pipe comes over the back-board under the sink and then down into the sink's waste pipe. Is there supposed to be a U-bend/upside-down U-bend above/below the the height of the washer outlet/sink waste pipe?

Thanks for all your replies guys - sounds like we're getting somewhere!

Cheers,

Steve.

Post a photo of under the sink and the connections, seen pipes running uphill before now Steve, and without wishing to offend the word believe doesn`t help us to help you, facts do mate.

I'm in with Hammers, hepVo's work wonders for this. That's unless the waste drains straight into a spigot on the trap. A photo would help no end.

Hiya Guys,

Thanks for your input - apologies for the delay in replying, I've been away.

Here's a photo of under the sink... hope this helps!

that looks ok it may just be the way the machine cycles the pump cutting into remove water during the drying cycle
youll learn to hate that bottle trap after the 5th time youve cleaned it out and the seal leaks every time
