"Used this for our square downpipes: it's unobtrusive and looks good; Easy to install, works perfectly, and contrary to other reviews, sealant is NOT needed if you install it correctly. It's a good price and ordering from Screwfix online for collection is great."
"I bought two diverters from another company which were half the price, and then this one. It fitted my needs well in my non-standard use. I was fitting a washing machine tap at the tank end so that I could turn the diversion on and off, so I needed the tank end to use a standard thread - luckily this was standard."
