Hey 

 

so a new connection is going in from the mains / meter. But I can use an old one until I flip it over to the new. 
 

I need to lay what will be the new mains feed into the house under some hardcore that I connect later to the stop tap and meter. 
 

what size pipe do I lay underneath that I can connect up later ?

Distance? 

We had close to 100m and used 32m mdpe and a high flow meter. Its a beast. Passed the water pressure and flow tests for the sprinkler system without needing a pump but I understand this varies massively from region to region.

Initially about 15m. 
then I need to add another run once built of about 40m 

 

no issues jointing that up later ? 
 

I just want to avoid digging up the hardcore later and lay pipe I can use and extend for completed job. 
 

32mm Mdpe makes sense to maintain pressure along the run from the mains : meter. 

We did that with no issues. Only thing I found was that all connectors are not equal. I used some cheap ones and they were absolute rubbish. Cant remember the ones we ended up using, but they were at the expensive end. I got the recomended brand of this website, so a search should bring up an old thread. Don't skimp on this.
