Waste pipe connections underground 2

[mechanical3010]

The attached photos show the floor drain/gully to which bath tub, shower tray, fan coil unit condensate drain, lavatories and bidet are connected. The distribution of the fixtures is such that necessitates the use of 45 degree bends to reach the floor drain. The question is whether there is any serious mistakes in the illustrations or could these pass?
Thanks in advance

Hard to discern from the photos, but there looks to be a number of plumbing code violations. You do not post where this is, so note that there are slightly different plumbing codes and interpretations.

1. You do not show vents on the floor drains.
2. The shower drain appears to neck down into the floor drain.
3. You need water seals.
4. There needs to be an air gap on the condensate drain.
5. It appears you are using electrical grade PVC (gray color), that would be a code violation as all materials have to be certified for the application.
6. All plumbing components should be of the same material. What are those orange fittings?
7. It looks like you have the incorrect pipe diameters. All of the fixture drains lines except the toilet should typically be 1.5-Inch. You have some of them changing diameters.
8. You need a cleanout at the end of the stack.
9. The fixtures should have vents to the roof, you don't show this.
10. Why is there a condensate drain in the bathroom?
11. The bathroom floor drain is optional for residential bathrooms. The floor drain should be 2-Inch size and vented. The floor drain has to have a trap.
12. You should not have the fixture drains going into the floor drain.
13. Slopes are not shown, but the drains should be vented within 3-4 feet of the fixtures. Allowed distance between fixture trap and vent.


Don't know where you are located but there appears to be numerous problems.

The floor drain shown in the center to which all the three fixtures are connected, has an integral P-Trap in the body, so a separate seal and vent in the bath tub and other fixtures are not provided. It is true that the floor drain needs to be provided a vent to protect its seal.
The condensate drain from FCU (that is in the room adjacent to the bathroom) is connected to the floor drain like any other fixture and since the point of discharge is upstream of the floor drain integral P trap, there would appear to be no strong reason to provide the air gap.
The Pipe materials are in compliance with the national codes for drainage pipe and fittings.
My main concern are the 45 degree bends used in the drains of various fixtures before they connect to the floor drain and would appreciate opinions and feedback.

It is acceptable to use 45 degree fittings in horizontal drain pipe.

However, the 45's in the pictures look like pressure fittings instead of DWV fittings. Pressure fittings are not acceptable.

Here is a better picture of a DWV 45:
