My builders will be starting the construction of a garden room soon, which will feature a toilet. I will be the primary user of it, but occasionally others (friends) may use it, so there is no guarantee the wrong kind of things won't go down the loo.
I need a pumping station to take the waste to the sewer over ca. 45 metres horizontally. The vertical lift is neglibile, if any.
One supplier suggested a basic pumping station (in the area of £600), which has a 50mm pump and 50mm discharge (for use with 63mm MDPE). However, I'm concerned if someone puts something down the loo the long MDPE may get blocked, which would be a pain to unblock.
When I asked him about macerators, he said: "The macerator pump has to have something to work against and without having any lift a normal macerator would not be much use. You can get macerators that can cope with a low dynamic head however they are quite expensive."
I'm surprised that not having any lift makes me worse off than if there was a significant lift. Is that really the case?
When I asked a related question on this forum a couple of months ago, someone suggested a (non-macerating) pumping station and 110mm pipework. When I asked the supplier about this option, he said that wouldn't work well either due to the drop of pressure going from a small bore (50mm) discharge to large bore MDPE pipework. My builder says the same.
Is there a solution that would give me peace of mind without costing an arm and a leg?
