We recommend uHeat for Underfloor Heating Systems, and The Wetroom Store for all things bathrooms and wetrooms. They provide discounts for forum members.
Welcome to the forum. Although you can post in any forum, the USA forum is here in case of local regs or laws
The Earth is under attack by Humans. We need to get smarter and work better when it comes to protecting it by plumbing wiser. Choose green products and processes. And you professional plumbers - you too need to help push the correct green products. Or at least offer it as an altertnate when providing a "dirty plumbing" job.
As well as our green energy forums on Plumbers Talk, we have the electrical side of green energy covered by our Electrical forum.
We recommend City Plumbing Supplies, BES, and Plumbing Superstore for all plumbing supplies.
