Walk in shower - pump leaves 1cm water visible in drain recess

[rknox007]

After showering in our new walk in shower, the pump that takes the water away leaves a centimeter of water visible inside the shower tray drain. (Please see picture below)

Is this normal? We are worried that since water is permanently lying in the drain recess that it will start to become unhygenic due to slime etc starting to grow.

After switching off the shower, the pump to take the water away stays on for 20 seconds, then after a minute the pump kicks in for another 8 seconds. But we still always have water left in the drain recess.

Can anyone tell us if it is normal for 1cm of water to be left in the drain recess (see picture), or is it a problem that we should get the contractors that recently fitted the walk in shower to fix?

Thankyou for your help, Rosina.

Well if pump unit faulty ,maybe would empty shower tray and then if non return valve faulty ,tray could refill, however, this, I think by what you are saying is not happening, maybe waste pipework could be incorrectly run
I am not sure but the chrome waste fitting does not look the right one for the shower tray, would have thought it should fill the complete recess area, maybe a special waste fitting required for that tray, hard to tell by picture, is waste outlet fitting, recessed in visible tray recess or just fitted on top
Either way all the visible water should be drained from tray ,to be installed correctly, what make of tray is it?
imho

No this is normall, its to stop the pump running dry, looks like some sort of akw shower tray wich looks like it has the correct cover over plug and sounds like you have a digital pump or ' digi pump '
also i imagine that as its a pump shower waste its only a shallow one, so you wouldnt have a trap seal, so this a
Upward Discharge

Yes double d it is an akw shower tray and akw digipump 4. Thankyou for the reassurance double d that everything is okay, I believe it is an upwards discharge too from seeing where the pump was positioned.

Thankyou for both your replies double d and puddle, much appreciated. Rosina.
