GENERAL LAYOUT OF A SHOWER INSTALLATION

A TYPICAL INSTANTANEOUS ELECTRIC 

SHOWER INSTALLATION

Plan your own installation carefully. Check on the 

nearest and most readily accessible rising mains 

water supply, this may be beneath the bath or in 

the loft, where it feeds the cold water storage 

tank. Use only the cold rising water main supply.

Do not connect the shower unit to the outlet from 

the cold water tank.

Avoid connecting the shower unit, if possible, 

where it will be affected by water drawn off by 

other appliances, e.g. From the mains feed to the 

W.C. This may cause a drop in pressure too low 

for the shower unit to work correctly.

An isolating valve must be fitted to comply with 

water regulations and for servicing purposes.
