Is it better to get pressure pipes rated for higher pressure than lower ones or in the AQ settings it wont ever max out PN6?
Im going to be running 4000l/h pump

The choice as I understand it is pressure vs stormwater pipes. This is mostly due to sizing of connections. In AP your not going to bust the PVC with pressure, especially with gravity feeding. I chose pressure as this is easier to look for parts and offers some protection against being stepped on. |

PN6 and PN9 are just pressure ratings in Bar In smaller fittings often they only make PN9 Storm or DWV are the other options but only in sizes over40mm I think for DWV, and only 90mm in Storm If your running 4000 lph, look to pipe sizes 40-50mm or youll have significant loss in flow and head delivered. No problem with DWV, just range of fittings not quite as big. Much cheaper though. |

Pn6 pressure pipe is available but is expensive because it is not a standard category. Dwv is rated at pn6 and will stand an equivilent head of pressure of about 60m of water. So unless your pump can lift water to a height of 60m pn6 or dwv will be fine. If any one knows the rating of storm water pipe I'd be keen to know. |
