Stone backfill cures that, you dont really want to connect them properly as it lets in silt from the old pipe, unless you know an old system is working fairly well you actually aim to cut the old system at 90 degrees if its possible.Our chain trenchers do at least neatly cut old unknown systems, this would ruin them and you’d never know?
Based on our experience stone is not always needed it's just more work and pain in the arse, water will still find its way into the drain with or without stone and the trouble is stone does and will block just like a soakaway and you can't clean it once it's underground.
No, can't agree with that. It is all dependant on soil type. I see pics on here of people draining 'wet spots' and they don't look that bad compared to some. On sticky soil types and clay stone is very important as a permeable layer for water absorption a V drain 1 metre deep filled to the top with stone regardless whether a pipe is used or not is giving 2m2 of surface draining area per running metre whereas a 4 inch pipe buriesd in the ground can only provide 0.314 m2 of surface draining which is less than a sixth as effective and perforated pipe clogs quicker than stone. Pipe on its own is effective if you are transferring water from point A to point B but not a good absorber on its own. We have tried all systems here for drainage and have had most success with a system that only uses pipe on the 'spine' drains on 'herringbones' and sheughs. The side feeder drains are all done with 2 inch clean stone to the top and no pipe. And for those of you who complain about using stone the last bit we drained before the weather broke needed a 6 inch twinwall drain pulled up the spine of the herringbones and stoned to the top, it took 4 ton per metre for the worst of it, dug till you get a hard bottom, stoned up for pipe fall, pipe put in then stoned to the top. It is drying it though.Based on our experience stone is not always needed it's just more work and pain in the arse, water will still find its way into the drain with or without stone and the trouble is stone does and will block just like a soakaway and you can't clean it once it's underground.

Out of curiosity what sort of price is one of those? Also is the pipe dear?This is the machine I use with an old 7250 magnum so 260 Hp
Not as clever but does the job. Only difficulty is getting a constant fall on the pipe. I never lay the pipe first time or even second time through only once I have pulled through blind at full depth

Thank you, that gives me an idea, at least it looks like it would be worth doing and be affordable to buy the machine, even if it is dear for what it is it is still cheaper than our American friend on here quoted further back up the thread!The short answer is no idea.
The long answer is I have had mine for twenty years now. I paid (I think) 32000 francs in 2000 and bought it with a young farmers loan at 2% fixed so only finished paying a few years ago, it was something like 300 euros a year for 15 years with payments only starting after the second full year.
Someone told me recently they had a quote for one but I can't remember exactly it was something like 8K which seemed a lot for a glorified subsoiler I thought.
The last pipe I bought was a few years ago and without looking think it was 80 to 100 euros a 250m roll of 50mm. It was cheapest by the lorry load.
I used to say it cost 300 euros a hectare at 12m spacing. We have a digger as well to do the joins and occasionally trench in a bigger pipe.
But as I say this was all a few years ago!
That was most definitely considered but we plan to be in the UK during that time to host plough demonstrations.It would be a very interesting webinar for my self and others, but it bang in the middle of our harvest period. I think you may get a lot more people interested if you repeated it in November.
