[AstonHill]

Hi
Want to run about a 45feet length of pipe in a trailer (one end to the other) of fresh cold low pressure water
What could I use that is cheep but will do the job? there will be several bends to it though

Answer (a): Hosepipe, guttering, buckets, hollowed out bamboo, repurposed extractor fan ducting, scaffold pole...

Answer (b): What are you connecting to at either end? What are you using it for?

https://www.leisureshopdirect.com/w...ttings/water-hose-for-caravans-and-motorhomes take your pick. There are many other sellers online and in physical shops.

Potable cold water would be best in blue pipe, or some other opaque tube to reduce mould growth. Modern caravan trailers tend to use 12mm with John Guest or Whale 12mm pushfit connectors.

BUT the use, flow rates requires and pressure of the supply all matter in designing a system.

What are you using it for?

I am running water from a holding tank and going into/ though the trailer to a water heater, 2 sinks and maybe a toilet, all will have there own header tanks

Is hose pipe a lot cheaper then hard hose like 15mm PVC pipe

Potable cold water would be best in blue pipe,

Do you mean alkathene pipe?

Modern caravan trailers tend to use 12mm with John Guest or Whale 12mm pushfit connectors.

But what do they use as the pipe?

Caravans use 12mm o/d pipes as it minimises the stored water from hot and cold water holding tanks and caravanners shower using the wet, soap/wash, rinse technique. {40 litre water barrels, 10 litres of hot.}
Whale, for boats/marine but not dissimilar to caravan/trailers: https://www.whalepumps.com/marine/s...ck_connect_technical_guide_specifications.pdf

Larger stores or mains water fed could use 'domestic type' 15mm pipework if it works out cheaper or better?

You do not want to skimp on the cheapest plumbing materials for a habitable space with drinking water involved. Beware of holding tanks and Legionella risks if the temperatures could be suitable for that. Don't forget insulation for frost protection, either.

You can select any of the pipework you wish from the supplier I linked to: 'food grade' pipe is a must if drinking from water out of it.
The 12mm semi rigid pipe (Whale style stuff) was in the linked list near the end iirc, but on the more expensive side cf the reinforced flexible 1/2 inch stuff.

So if I went for 15mm; should I go for PVC, blue alcaline or soft hose pipe?
