This is connected up to 20mm blue pipe and pumps very well, gives a good flow and cuts off when the tap turns off.I was worried it might not have the power, but it does. ### ⭐⭐⭐⭐⭐ Perfect pomp *by A***R on 9 January 2025* Good quality and easy fit ### ⭐⭐⭐⭐ Hose connection *by T***Y on 28 June 2023* It required a 33mm hose which can be ordered from here - lay flat hose - or fishpond hose. However, I used a 21mm grey washing machine drain hose from Screwfix as they have rubber cup ends which stretch to fit perfectly over the inlet and outlets, are very flexible and are reasonably cheap and readily available.
