Portable Dishwasher Faucet Adapter Fitting: 4 Steps

If you are planning for a new faucet adapter, make sure you try with the older one for fitting in. Also, check if you have removed the faucet aerator or not. If you have done it properly then the problem might be somewhere else.

To fit the adapter in the right place, you have to abide by a few simple steps. To know about it in detail, follow along.

First, it is very important to know the standard faucet size. It is different for men and women. The standard size is 55/64″-27 for females and 15/16″-27 for males.

If you want to determine the size easily, you have to remove the faucet aerator. After that measure its diameter. For the male faucets, you have to measure the outside, and for women measure the inside.

One important thing is, that your faucet and faucet adapter thread won’t be of the same size. If both the faucet adapter and faucet are the same and standard in size, then you need another thread. It will help to bind them together.

Step 2: Determine the Thread Size

The step to determine the thread size is pretty simple. All you have to do is to observe the position of the thread. 

If the thread is located outside of the faucet, then it’s a male one. In reverse, if it is located inside, it is the female one. 

If both the faucets are of the same thread type, even if they are standard size, they still won’t fit. The pair always has to be male-female type. Male-male or female-female type faucets won’t work.

Step 3: Examine the Portable Dishwasher

After determining the source of the fitting issue, it’s time for examining the dishwasher size. You should go through the manual and check what your dishwasher type is. You will also get faucet adapter options there. 

If you are facing difficulties in finding the tread size, just take help. Call someone from the company. Because you have to be specific and precise about this part.

If you are not ready to replace them you have to go for the custom-sized faucet adapter. It’s better to get professional help for precise measurements in the case of the unique faucet.
