It is a shame an Aussie company is so limited in their thinking.
If a product is of decent quality why not advertise it world wide?
I use lots of Canadian manufactured QUALITY plumbing products and would highly recommend Canadian manufactured roof drains.
When I had to give Merrell Lynch a full 10 year 100% guarantee on product and labour I would only trust Enpoco.
This corporation was the ONLY one to offer this kind of quality and put it in writing.
