How to recognise a quality polyethylene rainwater tank
Submitted by admin on Sat, 09/22/2007 - 07:42.1. Polyethylene rainwater tanks comes in many different shapes, colours , heights and sizes. Some are great for under the eaves, under decking, under the floor of a house. Some are specifically designed to be buried in the ground totally out of sight and freeing up the yard. Some have corrugated look, some are straight walled, some resemble brick walls. Some have special windows for strength (some remind me of puffed quilts)
2. Polyethylene is recommended for contact with food & water. It does not leach chemicals into your water. Fibreglass can break down & colorbond steel can rust. Bags & liners can be pierced.
