Shower Not Drainage Properly

[Rhbeen]

I am trying to solve the problem why my new shower tray after 2 months is not draining properly. The tray is fitted with a shallow water trap. It may be because of the water trap design, or the drainage out leading outside. The waste pipe is almost horizontal. Would that be the reason?

You need a better fall on your waste pipe.

The problem is that I have tiles over the bathroom floor. That would be the only access. Is there another way?

It will only flow away properly if you have enough fall on it, if its almost horizontal it won't (as you know).

If the waste is above floor level try raising the tray a bit to get the fall.

If its under the floor this could end up being a bit more involved. If you don't want to remove any tiles from the bathroom floor, you could always try getting at it from the ceiling below (thats if your bathroom is on the first floor of course).

Yes you are right. The bathroom is on the first floor. The point at which the drainage pipe exits the outside of the house could be the solution. What if i hammer away at the brick so that the pipe can be lowered a few cm on the outside of the house. Is this possible? If so, would this put a strain on any of the points on the drainage pipe, especially where the pipe connects onto the water trap?

If it's "after 2 monts" it's because it has a buildup of soap and hair gunge. That's what you get in 'flat' pipes!
Start off by rodding it (should have access through the shower grille for a drain spring) and putting a bucket of boiling water down it.

Some drain cleaners/Mr Muscle type products are pretty good.

PROBLEM SOLVED!!!! Used a drain cleaner which says on the bottle that it dissolves hair and soap blockages. The brand cleaner is called Buster.
