[ivanm]

i have a water feature with a oasis aquashift pump, when you swith it on the pump trys to work but does not pump the water,if you lift the pump out of the water and then place it back in the water,the pump works well and as it should
if you then turn the pump off and then on again the same thing happens as above
has anyone any idea why i cant get it to work properly all the time

Has it been primed as per the instructions?

 

[breezer]

you could try a new impellar., (assuming you have taken it out and clened it first)

i dont know if it has been primed, have just bought a new house pump was working fine when we viewed the house,ever since then it has not worked, how would you prime the pump

he means you have to get water in and the air out, something you have already done since it runs when you put it back under water and it continues untill you start it again

ivanm, have you taken the pump apart and cleaned its innards? Its really quite easy to do. The electrics are sealed for life, dont try to open that up. Depending on the model of pump, take the strainer off, unscrew a few screws behind the strainer, then the parts that shift the water should be visible. The driveshaft is magnetic and is held in its hole by the magnets in the motor, it can take some force to pull it out. Just take all the parts out, scrub them with clean water, and put back together. Beware though it can get messy - there could be years of decomposed algae and blanketweed etc in there, and fish waste. Also beware there are certain very fragile parts in there. This should be done every year.

If you couldn't i would not have suggested it.

Some times though it is more hassle trying to get one than it is worth.

being as the impellar is so small it has a central shaft which is thin, if something "big" gets is there it can ever so slighty bend it (even though the main impellar is on this shaft)
Being as its slightly bent it cant turn properly with the weight of the water, when you take it out of the water, there is no weight so it will start, and once it has started it doesnt want to stop.

A bit like pushing a heavy wheell barrow, once you have got it started its easy.
