Hello, I'm after advice from professional Water-Well pump installers.
Have a look at the attached diagram illustrating my Well installation. I am intending to install a 900W (~1-1/5Hp) Jet-Pump with a fully immersed Foot-Valve at a depth of ~ 5-6m (I'm roughly at sea-level). My concern is the horizontal distance from the pump-house location of the jet-pump to the well-head, some 4.3m (~14 feet). Many installions I've seen have the pump located much closer than this so I am concerned as to whether this may cause problems with adequate suction. I do not wish to move the pump-house closewr as this would entail a huge amount of expensive and time-consuming work (new foundations, electrical and plumbing re-connections, etc). NB There is no snow or freezing conditions.
Can anyone with long experience of these types of installations advise me whether my concerns are legitemate or whether there is nothing to worry about?
The pump inlet/outlet is 1"BSP (~25mm), you will note from the diagram that the inlet pipe through to the Foot-Valve is 1-1/4" ID so this will limit fluid friction. Also, (not shown) a non-return valve will be installed at the pump inlet. Any comments?
Thanks for all helpful replies.
