Bottle gully type

[Clint101]

Hi could anyone tell me what type of gully I need, I need it for the kitchen sink waste and the rain downpipe, will they need separate gully's or do I just attach the downpipe to the sink waste gully? And if so can someone point me In the right direction of the gully I need.
I have added pics there will be a raised deck eventually coming off the extension unto the blue brick.
Thanks for any help.

They should be separate, do you have a soil pipe nearby?

 

[Clint101]

Hi thank you for the reply

yes the soil pipe is shown it has the black cover on, what type of gully would I need for them both and how would I connect them.

I need help in finding the specific fixing I will need.



























I am lookine

OP,
Whether you combine the waste and down pipe gully or have independent gullies depends on where the gulley drain or drains discharge - into main sewer or a soakaway?

110mm Bottle gully is the usual gully for a rainwater downpipe (RWP).
The right hand pipe you show is not a soil pipe - its a RWP.
Does that RWP discharge into an existing gully?
What size is the lintelled over "waste" you show?
Have you located the nearest manhole? Have you opened it?

Regular bottle gully under each one.

Depends upon your property. The storm water should go to a soak-away. The foul waste into the sewer.

And if so can someone point me In the right direction of the gully I need.

 

[Clint101]

thank you for the reply, the pipe underneath the lintel connects direct to the sewer chamber, the rain water and waste all go
To the sewer chamber.So If I get a bottle gully like the one in Nosalls post for the rainwater pipe and then connect it to a bottle gully for the sewer waste pipe
(the one under the lintel) would I need something like this?

No, it needs a chamber where they meet.

 

[Ivor Windybottom]

Soil pipe should go to the centre channel to keep it clear and to prevent the risk of toilet water being pushed into the gully trap.

 

[Clint101]

Thanks for the replys,
I have drawn a crude plan of how it is at the moment. So between the sewer pipe end and the RWP I would need another chamber? With RWP bottle gully and sink waste bottle gully connected to this chamber?

 

[Ivor Windybottom]

You need a chamber for any junction.

Rainwater ideally needs to go to a soakaway, if that's not feasible, then a Surface Water Drain, if that is also not feasible, then foul/combined sewer as last resort.

If this is the case and you've been given permission by the Building Inspector to put the rainwater into the sewer, then I'd keep it simple. Fit an Bottle Gully, use a 90 and 45º bend to raise the height of the gully if you need to. Rainwater can be connected to the Back Inlet.

Ensure Gully is fitted right way round with trap on outlet, and rainwater to inlet. Support all pipework, suggest sit gully on blocks, and add some concrete to prevent any movement.

Surely a bottle gully is a trap within itself, and therefore doesn't have or need a trap?

The ones I've seen with a back inlet don't seem to have any differences between the outlet/inlet, they're just two spigots.

Arguably a bottle inlet is roddable so it may give some access. But that doesn't omit needing a chamber if it tees into a foul water drain, as it won't allow access to the other branch that it meets.

Sewers are sometimes the only practical option for rainwater, especially with a small garden and/or clay soil. Be aware that you will need to disclose this to your waste water utillity company, who will then add an additional "Surface Water Charge" to your bill for taking it away for you.

I think what Hugh meant was to make sure the trap in the gully is on the outlet side.
The inlet is slightly higher.

 

[Ivor Windybottom]

Ah OK, either mine are both at the same level or I've never noticed!

I'm avoiding using the back inlet these days, did it once but thought it was a bit dodgy. I like to generally stick to the principle that pipes should only ever get wider as they go downstream, in theory anything that can physically fit into the pipe should be able to flow out of it. Tipping into a bottle gully breaks this rule, as it has to fit down a narrow gap.

Thanks so much for all this advice, the building inspector is aware, and yes garden is very much clay. All the rainwater pipes from the older part of the house flow into the sewer, the house was built around 1960! I'm not sure if all foul water and rainwater was separated before 1960.
Thank you all
