Installation of a shower pump in loft - positive head vs negative head

tired_dad

Need some advice.

Want to install a shower pump on the loft floor in order to run 4 showers.

Will be installing a Stuart Turner - probable 3-4 bar pump into an existing conventional vented gravity system.


The Cold Water storage is on a high platform in the loft.

The loft is unused space. The 1st floor shower head height will be about 0.5m below the level of the pump. The pump itself will be below the level of the cold water storage.

The question is will a standard house pump (such as the standard 4 bar monsoon) do the job. The manual of this pump says it only needs 0.6l/min for the flow switch to activate).

Hope I have made my thoughts clear.

Kind Regards

One thing to flag up - when mounting the pump give some thought to the amount of vibration and whether you want to do anything to damp it like using rubber mounts.

yes, lots. Any advice welcome.

Currently planning a concrete slab with pump on top (pump to sit on supplied foam antivibration mat).
