Job on this weekend

[Jamie Banks]

Just wondering if there are any hints or tips needed for a job i've got on this week.

Got an underground drainage system to sort out:

I got 2 down pipes coming from the garage which I am running into a bottle gullies, from here I am going to run 110mm pipe under ground into a manhole/inspection chamber and then from the manhole back into the existing soak away that runs between one house and another.

So far I have the bottle gullies in place and 1 length of 110mm connected.

As the pipes are coming in from random angles was thinking of making/building my own manhole and was just wondering if there is any advice you guys can give me.

The other problem is that the existing gully/soak away has roughly 82mm connection and i have 110mm so think the only thing to do is to use a reducing flexible coupling.

Any help please - would be very gratefull

if its going to a soakaway and its purely rain water i woulndt bother with a man hole just join the ywo pipes with a branch and put in rodding eyes to make sure it can be cleared have you used roddable gullies ?you might be wise to put a small plastic inspection point just before it reduces down as this will be the most likley place to get problem they make small ones on the run of pipe with about a 12 inch cover
you dont give any indication of how long the runs are
