This item replaces a more expensive original. However it has worked very well in my installation. It seems to be made to the same standards as the original.

GBHelpful staff and and a good stock of Floplast fittings
After phoning several suppliers advertising Floplast fittings I found that On Demand Supplies were the only ones actually carrying any stock, The staff were very helpful in even finding spare gutter seals.

Easy purchase and a quick resolution to accidentally ordering twice. Customer service and communication was spot on. The part ordered arrived promptly and, happily, it resolved the heating system issues we'd been having. Great experience, thanks.
