Dehumidifier in to waste pipe

[Matt0029]

Is it acceptable to plumb the waste from a dehumidifier into to a waste pipe. It has a 9mm pipe with it for the waste. I was thinking of putting this on to an appliance connector waste Fitting then screwing onto a hepVo trap. A washing machine upstand maybe unadvisable incase it isn't used for a while?

What do the manufacturer's installation instructions say?

 

[Matt0029]

It says it can be plumbed in to the drain via leaving it to drip over a sink.

 

[Matt0029]

Would it be any different really if let to drip in to a washing machine upstand? Though drying out could be an issue

We have plumed in a number of commercial dehumidifier's water from them is regarded as grey water . Always used a hepV0 trap with an upstand .

Thanks do you mean hepvo trap and inline adapter?

 

[Matt0029]

With it being a constant dripped discharge when in operation would it not cause an issue with keeping the hepvo trap slightly open when in operation?

 

[exedon2]

Yes hepvo trap with adapter never had any problems.

 

[Matt0029]

The pipe from the dehumidifier is 9mm so won't go over a appliance connector the unicorn thing that accepts a washing machine hose any ideas of connecting this to a hepVo with inline adapter. Thanks

Condense pump waste adapter/ spigot

 

[Matt0029]

Thanks is that 22mm overflow on the larger size. Rigid?

 

[Matt0029]

So would fit in to a 32mm to 22mm rubber reducing bung?

 

[ShaunCorbs]

Correct or solvent your choice

 

[Matt0029]

Excellent thanks. Are this usually sold in plumbers merchants or more of an Aircon thing? I'll have a word were I go

 

[Matt0029]

The only one I can seem to get hold of is the one in the attached picture;

Does this look like the 22mm part is soft rubber i.e to attach to a pump with a jubilee clip? So may not be suitable.

 

[ShaunCorbs]

Nope not rubber same part to mine

 

[Matt0029]

Thanks I'll order that is a city plumbing near me. Can I just ask what people's thoughts are on hepvo traps compared to other similar waterless traps like viva, seem quiet abit cheaper.

 

[exedon2]

We have used the Mcalpine ones as you might expect well made but a bit bulkier.

 

[Matt0029]

Thanks do you usually use hepvo for dehumidifiers? Just abit conserned if it is a trickled discharge the membrane could possibly stay partially open?

 

[Matt0029]

The hepvo traps seem very good have only used copys for a few years. But they let the slightest trickle through. Seem to open easier then the other makes I have fit

 

[Matt0029]

The machine says just to remove the plug at the rear and attach the hose for permanent drainage. I thought they'd be something else to do to stop it draining in to the reservoir in the machine? But it doesn't say anything.
