Smell in new bathroom

Think you may have helped me solve a similar problem. Moved in to new house earlier in year and have 2 showers upstairs 1 getting bad smell now and again other is fine. Due to this thread had a look and the one that smells sure enough has a part missing in the trap looks like it’s a one way water goes through but seals if no water going through creating a seal. Can I buy this part seperate or will I need a whole new trap? Anyone know the make and or supplier of this type of trap. Pic of missing part attached

 

Update - looks like its WIRQUN

 

Ah! I see it all now. The chrome top is irrelevant.
The rubber seal part must go tight down in.
It seals in the first, larger diameter part I think.
Water goes down the open tube and up the sides to out, but the rubber seal prevents sewer gases.

 

The white wast pipe (tube) will sit in bottom in the water that collects there, hence creating a seal. Your right the silver cap does nothing but appears attached to the rest so all in one piece.

 

If the silver cap does come off then yes it is not needed as it will be concealed by the flat piece of white plastic in picture 3

 

There should still be a gap around and under the silver cap, water goes down through white tube and then up outer ring to waste pipe.

 

There will be no smells as there is a “water” trap at bottom of the unit, that’s what the white pipe is for, it sits in a inch of water or so.

 

The chrome part is usually removable. It is a separate part, so unless it was heat welded or solvent welded, it will just be a stainless steel bolt from underneath the cup part.

 

Just to refer to my earlier point, you may not have had nasty smells coming into your bathroom for the last 15 years as the traps on the previous appliances have been working well, but I'll say it again, your drains shouldn't smell nasty. They're certainly not going to "smell of roses", but equally, they shouldn't smell too bad. If they do, there's something wrong.

When I remove my own manhole cover, the smell I get is little worse than that from the inside of my washing machine. It certainly doesn't smell of poo or pee as that is all being cleared away into the main sewer in the street. But maybe other folks just have a different sense of smell from mine.

I'm glad you've finally got the shower trap sorted out in any event.

 

Any lingering smell should hopefully disappear once it’s all back in place correctly. Leave a window open if you have one and all will be good in no time as long as trap is doing it’s job properly !

 

Glad you've finally sorted the problem, that chemical smell is probably sulphur dioxide, plenty of ventilation will soon clear it

 

They are available as a spare,really need to measure it. They can vary . This company has some info https://www.plumbers-mate-sales.co....licone-non-return-valve---74000636-6312-p.asp

 

Yeah thanks rang around some local plumbers merchants who didn’t have any but plumbers mate in Eastbourne did. Wife picked one up this morning for £6.94. Fitted and hopefully no more smells. Thanks again, makes you wonder where the original went!!!
