I've fitted a 2nd hand Salamander ESP75CPV shower pump, which came without any flexi hoses. I have therefore piped 22mm Speedfit directly to the inlets via 22mm-3/4" connectors, and 15mm Speedfit to the outlets via 15mm-3/4" connectors.
The cold feed is separate from the (22mm) cylinder supply and is direct from the CWS tank. The hot feed is via a 22mm no stop Essex flange with the copper pipe bent upwards inside the cylinder. All connections to the cylinder are 22mm compression fittings using copper pipe for a short length (approx 150mm) before changing to plastic. All isolation is using 22mm full bore lever valves.
I investigated using tap connectors, however even the 22mm connectors seemed to have a small bore... I can feel only a very slight vibration through the pipes when the pump is operating. The system is working well so far.
Any opinions on whether the direct plastic connections to the pump will cause a problem over time, and whether I should therefore try and get some proper flexis?
Thanks!
