Help please, Ihave a Sterling europa 1994 Europa 450es.The shower has always worked quite well [Well as good as it gets!}but the last two trips the pressure has not been good ie when shower head in normal position the water is not there ,drop it down to knee high the water flows ok. any ideas ?Peter Derbyshire,ps the van has a Cascade 2 water heater.

Hi Peter.
It sounds like your water pump impeller is worn out. It would be worth replacing the entire pump.
Submersable water pumps don't like running dry and will wearout over time due to the barrell running dry and you only know by the change of pump pressure.

Check the pump on the external to make sure it isnt drawing air into the system, also lift the pump to water level to see if the pipe isnt split and squirting water, or change the water filter if fitted,also the pump will say a litres per minute somewhere on it, check it by running cold water into a measuring cylinder/bucket from the caravan tap as it may not be good enough....11 liters per minute should obviously give 11 litres of water in a minute.....
Hello Peter.
Contrary to Steve suggestion I have never seen the the impeller of a submersible pump wear out. and I have seen a lot of impellers from most of the common manufacturers. However he is right about submersible pumps not liking running dry.
Depending on the age of a pump, if it is quite old and it has run dry for as little as 2 to 3 minutes, irreparable damage may have been done to the main shaft seal.
This will allow water to enter the motor housing and when sufficient has got in the motor will deteriorate very rapidly and probably stop.
If the pump is still running satisfactorily, then other possibilities exist.
If there is a filter, does it need replacing?
has the hose split so its leaking water.
As for testing the flow rate of their pumps, manufactures rate the pumps with zero back pressure or zero delivery height. A 7lt/m pump will never deliver 7lt/m through all the restrictions of the filter, and pipes and taps and the head height. the hose has to be removed from the pump to actually measure the flow rate.

I had a similar experience, but when I pulled the hose leading to the shower head taut it worked properly maybe a kink in the hose? I haven't investigated mine further yet!
Are you certain the pump is running as water from the hot water tank will come out of the shower head without the pump running. Could be the micro switch is faulty.
