Water system compatibility
The type of shower you choose and its performance will be influenced by your water system. For example, if you have a gravity fed system and want to install a Thermo shower, you might also need to consider fitting a pump to boost flow and pressure. However, if you have a mains fed water system, you will not be able to add a pump to your installation.
There's a shower to suit everyone, but taking time to identify your water system now can save a lot of time and expense in the future. A qualified plumber should be able to give you good advice and for further guidance, why not check out the below links?
