Dishwasher plumbing....need advise

Dishwasher drain hose is connected to drain pipe rather than
the garbage disposal…Is this acceptable?

It can be connected to that drain pipe but it still needs either an air gap or high loop prior to the connection.

Yes, in fact some jurisdictions do not allow connection directly to the disposal.

No visible air gap device. In California there must be an air gap device, a high loop is not acceptable

the fitting shown is actually called a dishwasher tail piece…it is perfectly fine, but as others have said that drain line needs to be fastened as high as possible in the cabinet.

The more expensive dishwashers have the high loop built in and no air gap is needed in many areas.

Be careful when reporting something as wrong unless you know for sure.

What the others said David however is there any way you can upload better res pictures in the future as I notice yours are all very small.

Do you use your phone camera?

Yep. Chuck is correct.

Connection to the drain line is allowed, but it must first go through an airgap, mounted above the flood-level of the sink.

Thanks everybody for the feedback…

Very true Bruce, event the not so expensive models. What I’ve noticed this year is most new models have a “built-in” high loop.

Regarding connecting at GD, that’s prohibited in Illinois.

So with that being said, how do you determine which units “have it”? Or don’t you? What, if anything, goes in your report if you suspect the unit has a high loop built-in?

In CA, it doesn’t matter whether or not it has a high-loop - built in or not. It must have an air gap fitting installed above the flood level of the sink.

Understood.

My question was aimed more at Chris or Bruce regarding how they report what they cannot visually verify.

If no air gap (high loop) is visible I report as such. Note: Some models have a built-in “high-loop”; recommend to verify with owners manual.

As I suspected. Thank you.

The U bend is where the waste water would you, you would need to get something to split that aswell. The other pipes to put clean water should be attached to the taps, youll see a red bit and a blue bit - these are where your washing machine would connect to for hot and cold water. Those are what need split aswell for both appliances to use the water.

Thanks and Regards.

2009 IRC P2706.3 Prohibited waste receptors. Plumbing fixtures that
are used for washing or bathing shall not be used to receive the
discharge of indirect waste piping.
Exceptions: 1. A kitchen sink trap is acceptable for use as a receptor
for a dishwasher.
2. A laundry tray is acceptable for use as a receptor for a
clothes washing machine.

Commentary: *For sanitary reasons, this section prohibits discharge
of indirect waste piping into a sink used for washing or
bathing purposes. However, this provision does not
apply to the indirect connection of a dishwasher to a
kitchen sink because a dishwasher essentially performs
the same function as a kitchen sink. By the
same logic, this section also permits a clothes washing
machine to discharge into a laundry tub (see Commentary
Figure 2706.1).

P2707.1 Directional fitting required. Approved directional-
type branch fittings shall be installed in fixture tailpieces
receiving the discharge from food waste disposal units or dishwashers.

2009 IRC P2717.2 Sink and dishwasher.
A sink and dishwasher are permitted to discharge
through a single 11/2-inch (38 mm) trap.
The discharge pipe from the dishwasher shall be increased to a
minimum of 3/4 inch (19 mm) in diameter and shall be connected
with a wye fitting to the sink tailpiece. The dishwasher
waste line shall rise and be securely fastened to the underside of
the counter before connecting to the sink tailpiece
.
*
Commentary: *Dishwashing machines may connect
directly to the drainage system and do not require
an indirect connection by drainage air gap or air break
.
The direct connection is acceptable, because the potable water
supply is adequately protected against backflow. This
section requires that the waste line be looped as high
as possible and be securely fastened to the underside
of the sink rim or countertop to minimize the potential
of waste backflow into the dishwasher unit (see Commentary
Figure P2717.2).

2009 IRC P2717.3 Sink, dishwasher and food grinder. The combined
discharge from a sink, dishwasher, and waste grinder is permitted
to discharge through a single 11/2 inch (38 mm) trap. The
discharge pipe from the dishwasher shall be increased to a minimum
of 3/4 inch (19 mm) in diameter and shall connect with a
wye fitting between the discharge of the food-waste grinder
and the trap inlet or to the head of the food grinder. The dishwasher
waste line shall rise and be securely fastened to the
underside of the counter before connecting to the sink tail piece
or the food grinder.

  • Commentary: *This section permits a single 11/2-inch (38 mm) trap to receive the discharge from a sink, dishwasher and food
    waste grinder. The discharge piping from the dishwasher
    must be a minimum size of 3/4 inch (19.1 mm) and connect
    to a branch tailpiece of a kitchen sink or directly to
    the food waste grinder. For the same reason discussed
    in the previous section, the dishwasher waste must rise
    and be securely fastened to the underside of the counter

    before connecting to the branch tailpiece or food waste
    grinder (see Commentary Figure P2717.2).
