Tried making it with gv steel pipes. Its quick as dont hv to wait for cementing.
Used bicycle pump. Firstly plastic bottle brust at 7 full pump. Very strong pump.
Used second check valve at tail to use as a lid to fill the platic bottles.
Pressurised the second platic bottle tank to get more range.
Hope i will improve with coming attempts.

Welcome to WaterWar.net. Looks heavy from all the steel fittings.

If you've already had a burst then I'd recommend not using plastic bottles. Where do you live? We might be able to make some more specific suggestions.

Very interesting. Do you have any videos of it in action? How much water does it move per pump?
