Macerator
Hi, ref macerator outlet pipe, I'm running the out In 40 mm pipe, but was wondering if after the initial 3 meter rise it would be best to continue horizontal run through loft approx 18 meter in 40mm or 110mm soil pipe. Thanks

There are a few contributing factors here that would determine my best answer but from the information given and as long as you aren't going back to 40mm pipe then yes carry it on in 110mm. Probably best with an easily accessible rodding access point
The macerator is pumping the waste water from the macerator to the soil pipe if it’s pumped up to the loft and then running horizontal to the soil pipe as long as you have a fall on the waste pipe it won’t make any difference if it’s 40mm or 110mm
