are there any reasons for or against using quality plastic plumbing on board please ? I was considering Hep2O - http://hep2o-uk.wavin.com/

The present system is old manky copper and all the pipes and taps need replacing. Single freshwater flexible tank to 2 pumps (one a standard foot pump to the sink for veg and washing, the other a General Ecology hand pump to provide filtered drinking water.

I do not have running hot water on board (boat is too small to merit the complexity) and a pan of hot water is sufficient for normal ablutionary activity :eek:

Or should I use transparent, reinforced, flexible, plastic pipe ?

ta, team :)

i have Hep2O for the main pipe runs
 
Pushfit (not which exact system) does seem to be used a fair bit on new boats. I can't see a problem with it.

EDIT: I wouldn't advise transparent hose, as allowing light in may encourage stuff to grow.

My 1998 boat was all hep2o from new ..... no problems
 
I use it all the time for water based heating systems, better than copper in my view as the joints have more resistance to vibration and movement also much easier to run. Just make sure you use a proper slice to cut the stuff and always use the pipe inserts at joints, There are many push fit barrier pipe systems on the market to choose from not just Hep.
 
My 1997 boat looks like it was 'the other' make of push fit plastic fittings. Very similar to Hep2o. Still good even after pulling the pipes around a bit :eek:
 
Hep2o fitted on my previous boat in 1983 - it had just been introduced to the market. No problems ever. Main advantage, doesn't split when frozen, unlike copper!
Now the norm in all domestic property as well.
 
Not not suitable for drains to hull fittings, IMO. Otherwise, fill yer boots. The worst thing that can happen is you leak your FW into the bilges, which is only a problem on seriously long passages.

Have considered doing this but wasn't quite sure how to make the connection to the flexible tank. Any suggestions?

What fittings does the tank have already? You can go from pushfit to BSP threads, and most things ought to be adaptable from there.

I have seen problems with hep fittings on boats and in houses so we stopped using them. We always use JG speedfit with no problems and the fittings are removable & reusable and white which makes the installation cleaner!

It's currently got a hose spigot, ie the hose is held on with a hose clip. Can you get a push fit hose spigot so I can use a short length of flexi hose to cope with the movement of the bag?
 
I've still got half a roll of the stuff in the shed from when I rebuilt the bathroom. Perhaps I should replumb the new boat with it.

Recently did a boat the size of a house (8 off 600 x 800 double panel rads, towel rad + 120l calorifier) with the JG speedfit stuff, really nice to use and available from Screwfix off the shelf. Tested it at 5 bar for 4 hours and not a sign of a leak except one where I forgot to tighten the collar the final twitch. I had no problems getting any fittings and the install was a mixture of JG & copper tails, BSP fittings, hose tails. I've never really had issues with any of the other stuff having said that. The Rothenberg plastic pipe slices make light and neat work of the job and are very cheap, I've always used a ratchet shear cutter in the past and it did tend to flatten the pipe a bit.
