there are several aspects about low pressure :-
- if owner does not want to buy a proper power-jet shower unit then, if the shower is really a dribble, a small power pump can be attached to most showers (or,rather the piping behind). With labour, 200-300 euros and should last for years.
Sometimes, this task can be more difficult and thus more expensive if access to pipes behind shower unit is difficult. In which case it's back to buying a proper new jetwash shower.
However, neither installing a power jet unit or fixing a small pump are of much use if there is little water pressure from the mains to the property. You may find the tanks empty half way thru your power-shower
This is often the case with higher-floor apartments, or properties on hills, more so with older buildings. This may be especially true at present with water pressure being low in much of the country.
Mind you, you say the previous tenant always had lousy pressure.
As I said in my previous post i installed a large reservoir tank with an additional pump to shoot water up to three apartment in a building I own. However, if the owner has just one apt in a complex then that would be difficult.
I hadn't realised that the agent hadn't contacted the owner ,in which case my ire should have been directed to that silly person in the agency....
However, still put your comments in writing and state that you expect there should be a proper working shower within xyz period. It's a reasonable expectation.
