Components Of Kitchen Plumbing

In order to have a piece of thorough knowledge about kitchen plumbing, it is really important for you to understand the various components of kitchen plumbing so that you can not only make the BEST choice but also do the needful accordingly.

Kitchen Sink

It goes without saying that a kitchen sink is one of the most important fixtures in your kitchen if not the MOST.

Well, if youll closely watch the strainer body, youll mainly find a rubber gasket and a locknut beneath it.

These are connected to both the strainer sleeves and tailpieces.

All of these leads to the trap.

So, if youre not aware of what the trap is, then please allow me to explain it to you in the simplest way that I could.

The trap is nothing but the region where things that are not supposed to go down the drain fall.

Cleaning a trap is easier and can be expedited in an epigrammatic span of time, thanks to the clean-out plug on the bottom.

In fact, it then winds back up and is connected to the pipe that takes the dirty and used water out to the sewer system.

Kitchen Sink Maintenance

Check The Drain Outlet Height

Double Kitchen Sink Plumbing With Dishwasher

Before removing the old sink and buying a new kitchen sink, it is a good idea to check the height of the trap arm on the old sink. The trap arm is the horizontal piece between the U-shaped trap bend and the branch drainpipe in the wall. It connects to a sanitary tee fitting in the branch drain and should slope down toward the tee at about 1/4-inch per foot for proper drainage.

Measure up from the floor or base of the cabinet to the center of the trap arm. If the height is more than 16 inches, you may find that a new sink will not allow for the necessary downward slope for the trap arm.

Why Is My Garbage Disposal Backing Up Into My Dishwasher

If you have a single-drain sink with disposal and dishwasher, you may experience waste from the disposal going into the dishwasher. The waste enters the dishwasher through the drain hose that links the dishwasher to the disposal unit. It happens when a clog occurs in the disposal, leading to waste backing up into the dishwasher.

You can prevent such problems by pouring hot water down your drain once a week to loosen and wash away clogged debris.

Contact a local plumber to discuss your options for a disposal system and find the right one for your home or business kitchen sink.

How To Install a Kitchen Drain Trap Assembly with Dishwasher Tailpiece

Before you attempt to clean or fix your current plumbing problems, be sure to unplug your appliances from their power supply to minimize the risk of electric shock and injury. Turn both the cold and hot water supply valves off to prevent any water flow to your appliances.

It is also important to know that the running water in both your kitchen sink and dishwasher flow out through the same drainage line. So any clog or blockage within that main drainage line can cause water to backup and overflow into your kitchen sink. These clogs typically occur in four places: the dishwasher, the garbage disposal, the sink, and the air gap. Clogs in any of these four locations within your plumbing system can result in water filling your sink when you run your dishwasher.

First We Had To Pop Out The Old Ugly Sink

This was the part that sucked the most. You are underneath the sink unscrewing clips that hold the sink in . You also have to disconnect the pipes. We had a 2 drain system .

We untwisted the garbage disposal first and then disconnected the second drain & the water lines from the faucet . Once we were totally disconnected, we removed the sink. It came up easier than I thought. My husband kind of bumped it up from down below and with a nice big pull the hideous sink was history!

We were replacing it with an awesome white sink basin that I found sitting on a shelf at my Habitat for Restore Store. It had been a display at Lowes previously and I got it for a steal!

Plumbing can get hard sometimes and people may choose to install sinks in other places in the kitchen.

If there is a window blocking a vent pipe there is a procedure that needs to be followed to install the vent pipes. For the vent to clear the window the vent is run horizontally. The route then returns to vertical when the vent clears the window. A slight and upward slope should be included in the horizontal section because it cannot slope downwards.

The following is the procedure of venting kitchen sinks under a window. every step is important and should be followed carefully.

  • In the sink drain line that is inside the wall cavity install a sanitary tee. This sanitary tee should not be installed using a length that exceeds three and a half feet from the bottom of the P-trap. The PVC sanitary tee should also be used for a 2-inch waste-line. Use the PVC cement to glue the pipe coming from the sink and the sanitary tee together. The continuation of the drain should be glued to the other side of the sanitary tee. Here, ensure also that the 1 1/2 inch port is facing upward.
