Hi All
There have been previous discussions on the installation of a basement shower using a macerating system.

A common issue has been the elevation/slope of the shower to drain into the system and the resulting need to raise the shower base accordingly (6-8 inches to accommodate a p-trap)

The homeowner (like me) ends up with choices that are:

Break the concrete slab and drain it correctly $$$$

violate the code for either the p-trap or the min height from shower base to ceiling (6'-8") in most places due to a lack of overall headroom. Additionally, a shower that is only 6' in height will be awkward.

I discovered this shower drain that is European and is low profile.

It comes in two versions - membrane seal (not recommended in MANY forums) and a water seal.

Looking at the spec sheet/diagram it appears it uses a p-trap type of construction with a ring of water that gets displaced but maintains the "water seal" functionality of a standard NA p-trap.

My questions:

1- is the volume of water maintained as a part of the seal a significant contributor to the effectiveness of the water seal ?

2- How much grief will I end up with trying to mate the fittings?

All advice is appreciated.

The only approved side outlet drain I know of is made by Quick Drain USA. Proline.

I have only installed one of these in the past five years.

Turned out all right.

The drain was too short for the shower so I went a little cowboy and designed the shower base to accommodate a custom drain top install.

ACO makes one as well special order - but I have never held one or installed one as yet.....

IF I interpret the drawing correctly, it is a version of a "bell trap" and they have been illegal since before I was born. If there is a problem with the "P" trap, make an opening in the floor for it to fit into. In other words "Lower the river, don't raise the bridge".

Good day, I have the same issue as Mikey from above and I would like to lower the river. My question is would I have to fill in the hole with cement once I install the p-trap in the hole? If I don't, would water possibly come out? My basement floor is not humid so I don't know if water coming out would be an issue. Thank you for your advice. Martin
