Aco drains

Kf 1958 · 14 Apr 2021

Hi, hoping someone can help me.....

I am having a new patio laid and the guys laying it have installed aco drains around the edge of the house...which is fine.....BUT I previously had my sink waste pipe, washer waste pipe and dishwasher waste pipe concreted into the outside drain. The landscapers have now just chopped my waste pipes about 2” above the new aco drain, which I have a feeling is not right as not only does water splash everywhere but I dread to think what may come out the sink waste pipe!

Could someone offer any advice how these pipes should have been dealt with?

Thanks

You don’t want them into a aco, can a gully trap be fitted

Thank you for your advice -the Aco has been connected to the original drain that the pipes fed into, would this be the gulley trap? Sorry but I don't understand gulley traps etc

The rats are going to love this arrangement!

And if it's not trapped, then you definitely wont

90% of ACO’s are bodger onto the drains.

Have they sat it ontop of the old drain and cut a hole in the bottom of it so the water flows through?

I may be back on here with their responses to get further advice....thanks again everyone

Don’t forget your camera.

Better if you can post some pictures, but ideally, the old gulley should be removed, and new plastic gulley fitted to accept the waste pipes, (which need to discharge below the grid, but above the water line.

The ACO drain can then be connected either by using the bottom outlet option into a 'Tick Trap' and then via a junction into the drain, or if using a 'Bottle gully' via a horizontal outlet into the side bosses of the gulley. Either way, the Gully and the ACO drain must be trapped to prevent sewer odours coming back up.

From your description, the arrangement the 'Builders' have left you with does not meet Building Regs, and will create an unholy mess very quickly! Get it sorted properly before you pay them!

So sorry, I’m back...
So previously all out outlet pipes were concreted in and obviously drained water away from the sink, washer and dishwasher.

I have just spoken to the guys and shown them the advice I have received saying my son had sent it as they are still working here and want to keep good relations at the mo..... they have said that the aco drain they have fitted feeds directly into the old drain the pipes fed into and there should be a water trap on that.

Although the pipes have been cut above the aco drain they are going to be replaced and will feed below the top cover grid.

They are also saying if there was going to be an issue with the smell that we would already smell it....

As I say I have no idea about drains....more a shoes and handbag girl lol

thanks again everyone......btw two pics, one is original piping the other is what we currently have

Your gully trap is under the blocks now so it it ever did block you will have to dig it up to access it. That’s the round but you see on the ‘before’ picture just out from the house.

+1 for Ian's advice. Not an ideal way to do it, I actually went to a similar setup this morning, after being asked to unblock it. Trap was blocked with crud from the sink, soon cleared that, but the build up of congealed gunge was not pleasant, and that was with one waste discharging into it, directly above the outlet.

Personally think these are fine for rainwater, however grey water, and especially kitchen wastes needs to go into a proper gulley.

I'm with the others! it won't be long before that's a problem if left as it is.

Your household waste should be the primary concern and it should be into the gully (with access to the trap) and gone as swiftly as possible. The acos serve a secondary purpose and should be dealt with separately and have their own drain.
