I need to replace this:

existing horizontal pipe is 140mm OD clay pipe so I assume 4" internal?

I also need to add a branch to a slot drain from a new slate patio.

I was thinking this:

or this:

I'm not sure i'll have enough fall for proposal 1 hence proposal 2. I will fit the piece of slate on top on the slot drain sump with a sand only bed so that it can be removed for cleaning.

I also need to replace a bottle gully on the other side of the new patio:

with a similar setup but with a standard bottle gully.

any advice would be much appreciated.

Looks like you're doing well on your own. Option 2, you will need two of them fittings

For anyone doing similar. I thought I'd post what I did.

Second gully replaced with this

First gully replaced as per my option 2

Patio going in. Every piece of slate is a different thickness and size. I used a bridge tile cutter which I certainly couldn't have done the job without. Cutter was a Rubi Dc 250 850. Amazing tool.

Slate purchased from Berwyn Quarry in Wales as offcuts.

Pointing was done using gthk VDW800 2 part resin mortar colour Basalt. Great stuff and highly recommended.

Hopefully this will help someone

I forgot to mention, I used 2 x 25KG tubs of Pointing mortar and only just had enough. Patio is almost exactly 20m2. I am not going to work out the average size of slab. Joints are 12mm.

I also treated the slate with VDW950 prior to Pointing. I used about 1 litre for the 20m2

The slate is a mixture of finishes.

Polished/honed, sawn and riven. I tried to get an even spread of finishes but had to work with what I got from the Quarry.

The Quarry supply pallets of offcuts which are approx 10m2 per pallet which I found to ring true. I order 3 pallets and discarded a few pieces that I thought were a bit too thin for my application (approx 20mm). All the pieces I used were between 25mm and 45mm thick. I still have a bit left which o am going to use on a smaller section of patio elsewhere in the garden.

Anyway I hope this helps someone.

Would of liked to see some easy bends on the drainage .

Thanks for the praise. Not in the trade no. This is the first patio I've done.

I've never heard of easy bends but will definitely look at those next time I do underground drainage.

A 100ml 90% bend in a run is not rodable an is susceptible to blockages. A 15 %bend at both ends would of been more preferable. Where your 90% bend is should of been an I C for change of direction. There are those out there who would say : " it is only storm water but i don't subscribe to that school of thought. All drainage, regardless of it's use, should be laid correctly.

I see. The originals were there for 60 years without getting blocked so hopefully I won't have problem. If only you were here when I was still just planning. Thanks though. At least I know for next time.
