Would like a 1000L in 2-3 hours if possible Steve
Twin 4040 pumped to get it that quick. The pressure in mk is not good so you need it pumped. A single 4040 should still be good mind. I'm getting about 300 liters an hour
definitely 4040, if your water flow/pressure isn't good enough going to struggle to get that even, with a booster should get between 200 and 350 litres an hour.
could do with checking water pressure, as they have pressure regulating valves on most estates/areas, so depending on how hilly it is where u are, you may be good, or not so.
