I am currently creating a dog run along the side of our house. To enable the area to be reguralry cleaned with a preasure washer I am planning to lay a ACO linear drain along one side.

Fortuately there is a downpipe from the house guttering (80/90mm or so) leading into a 110mm plastic drain pipe near by. My plan is to connect into this 110mm drain, but my question is how?

I have seen your page on using adjustable couplings, but these seem to be used mainly for clayware. Is there any products out there for connecting into plastic?

The only other solution I can see, is to dig back along the pipe untill I have enough movement to fit a normal double socket T piece. But this seems a lot of work if it can be avoided.

Which Aco channel are you using? There are specific components available to help connect the linear channels to an existing drainage system in a variety of ways.

Some of the more common methods of connecting are shown on the Linear Drains page, and you can see a channel being connected using a uPVC trap fixed to a bottom outlet on the channel. Would this be possible?

I should point out that, as you are washing down dog excrement, you might want to consider connecting to the FOUL water system, rather than the usual Surface water. If you do, then you should incorporate a trap at some point.

Tony, thank you for the reply.

I have spoken to the BM that I am using and they have told me that it is a Liberty drain. Have you heard of this manufacturer, as I have been unable to find anything on the web.

I hope not to be washing solid dog waste down this drain, only dog pee. Therefore I was planning to connect to the SW drainage. I am planning using a trap as a matter of course (it shouldn't cost much more and hopefully won't take to much longer). If the drainage channel doesn't have a bottom outlet then I will use the sump unit that matches the drain. (I have checked and the BM has one in stock.)

My main area of concern is how to connect into the existing drain pipe. As far as I am aware a normal D/S connector is upto 100mm longer than the gap I need to cut into the existing pipe (in order for the existing pipe to fit inside the connector). For me to fit this type of connector I will need to dig back along the pipe to get enought movement to be able to fit the connector. Is there any type of coupling connector designed for use with 110mm plastic pipe that I can use to avoid the above mentioned digging?

Adam-

You're going to need a channel with a plastic grating as dog urine is extremely corrosive- it'll burn the galvanising off a steel grating in weeks. The only channels out there with plastic gratings have plastic bodies, which are stronger, lighter and more robust than traditional polymer concrete.
If you use ACO DriveDrain channel with a plastic grating, there is a movable 110mm vertical outlet attachment (part no. 30404), which will plug stright into the drainpipe. If you're interested in watertightness, the system can be sealed with any good exterior-grade silicon sealant.

If you need a foul air trap, you'll first need a sump (82959) and then the trap itself (2640). Any ACO stockist should be able to get these for you pretty quickly. I'd suggest that any smell from sending this to a rainwater system may get masked by the surface soiling, but it's up to you.

Finally, the gutter downpipe can be run straight into the top of the channel- you could even use a holesaw to cut a hole in the grating if you like, and this would avoid splashing.

Hope this helps.

I'm not familiar with Liberty drains, but there are so many of these items flooding onto the market (no pun intended) at the moment, that I can't keep track of them all.

Without seeing the exact layout of the drainage to which you plan to connect, I can't say that such-and-such a fitting is what you need. There's a lot of variation amongst uPVC fittings, so that while a standard fittinmg may, as you say, be 100mm too long, a compatible fitting from another manufacturer might be just right.

Can you get me a photo or a sketch of the layout?
