Macerator problem,shower slow to drain.

[Jason Lee]

Hi, I've installed a macerator a while ago to manufactures specs, toilet, sink and shower.
One problem I've always had is the shower tray is slow to empty and has over flowed a couple of times.To get around this if I run the sink tap at the same time all works fine and the shower tray does work as it should.
The toilet is not used for solids if you know what I mean.
I've checked the shower trap for hair etc all clear..

Are you sure the shower tray has been set high enough above the inlet to the macerator?

Hi, Yes.. I even rested the Macerator on the joists and have a raised shower tray..Do you think if I raise the shower tray up more this would help?

Have you complied with the macerator instructions?

From memory last time I did this the tray had to be something like 200mm raised - but the instructions will tell you for your model. It worked fine when I did this.
