Loss of power

aquastream mark two

the shower has lost it's power, I have followed your instructions and confirm that we have power. I have replaced the pump and this has not solved the problem. What is the next item that may need check/replacing?

Please advise ... RWK

Check that the hose and head are clear ( the hose can collapse internally)

Remove the on/off knob should just pull forward however it can be a bit of a bu**er then remove the 4 screws that hold the temperature knob in place, remove the temperature knob and then you will see the colour of your cartridge.If these are OK then you probably need a new cartridge.

If you already have the cartridge and want to carry on and replace it you will have to turn the water off to the shower.

Then remove the cartridge you will need to remove the 4 large screws at the side of the cartridge these have posidrive or ‘Torx’ T25 heads depending on there age.

Pull the cartridge forward to remove.

Before fitting the new cartridge you should replace the small ‘O’ ring at the rear of the body this is another bu**er to change……(something like a crochet hook or the sort of thing that dentists use will help)

It is not always necessary to replace this ring however if there any problems with the cartridge, the first question you will be asked is did you replace the ‘O’ ring? if the answer is no! then you will be told to phone back once it has been replaced.

When you refit the cartridge make sure that the slot, (usually on the right of the body ) the gasket and the body all line up properly then re-tighten the screws.

On the older versions you have to reuse the original brass screws if you have this type be careful not to over tighten the screws because the brass inserts in the body may split, on a few occasions you may find they have split when you remove the old cartridge if this happens then you will probably have to replace the body.

Refit the temperature control knob (new screws supplied) the fit the on / off knob, turn the water back on and check for leaks, if everything is OK remove clothes and have a shower!!!
