Excellent piece of kit does exactly what it says just follow the instructions and job completed under 10 mins
Really easy to use and saved many hours labor draining down a 12,000 litre storage tank
I was a tad wary buying this 22mm version due to the cost but the hassle of draining down a 2000L biomass heat tank made me take the plunge - video on the official site show 2 mins to fit, i took a few mins more but it does exactly what it supposed to !
