I am having a problem with the water filter. I just replaced that water filter and when I get water, it makes a high pitched kind of whistling sound. I have tried several new filters and same thing with all of them??

The high pitched whistle that you are hearing from your Rigid shop vac with a long hose may be due to several reasons. Here are some possible causes:

1. Airflow restriction: When you use a longer hose with your shop vac, it increases the airflow resistance, which can cause a whistling noise. This is because the motor has to work harder to maintain suction, and the increased resistance can cause turbulence in the airflow, creating the whistling sound.
2. Hose size: The size of the hose can also affect the whistling noise. A smaller diameter hose can increase airflow resistance, which can cause the same issue as a longer hose.
3. Clogs or blockages: If there are clogs or blockages in the hose, this can also cause the whistling noise. Check the hose and attachments for any obstructions, and remove them if necessary.
4. Vacuum motor issue: In some cases, the whistling noise may be due to a problem with the vacuum motor itself. This could be caused by a damaged impeller, a loose fan blade, or other issues with the motor.

To fix the issue, you can try the following:

1. Shorten the hose: If possible, try using a shorter hose to see if the whistling noise goes away. A shorter hose will reduce the airflow resistance and may help to eliminate the noise.
2. Check for blockages: Inspect the hose and attachments for any clogs or blockages. Remove any obstructions that you find.
3. Clean or replace the filter: If the vacuum filter is dirty, this can cause airflow resistance and make the motor work harder, leading to the whistling noise. Clean or replace the filter as necessary.
4. Check the vacuum motor: If none of the above solutions work, you may need to inspect the vacuum motor for any issues. If you are not comfortable doing this yourself, you can take the shop vac to a professional for repair.

check for debris in the air intake. I've had leaves in mine make a similar noise

Hi Basil,

I am sorry to hear your machine is emitting a high pitched sound. Based on the details you provided the problem may be isolated to the post motor filter, if so a new filter will be needed. We would like to help with this. Please contact our Helpline to speak with an expert:

I have an AquaStar tankless and it has started making that high pitched sound when in use. I wonder if that means I have clean the heat exchanger. I called Bosch but they won't help since it is installed in a bathroom--in violation.

The holes are probably clogged from hard water. Take the whole head assembly and dip it in a bucket of CLR for an hour or so. Then rinse off and give that a try. If your cheap, you can use a bucket of white vinegar and a little bit o water, but the smell is most disagreeable.

I had exactly the same problem. Just turn down the water pressure @ the valve on the water inlet line. While you have the toilet lid off, you may want to remove the fill valve (1/2 turn counterclockwise on the plastic nut attached to the water-in line), and clean the rubber diaphrams (there are 2). They will sometimes get gritty and this will cause some fill noises and leaking.

this is the line lin coil needs replacing

Try changing refresh frequency, color depth or resolution (wait for the whistle to appear before testing). Admittedly, you might have to give up some image quality - less colors, or less resolution. There is probably a problem in the TV syncing mechanism - if you can, try getting it replaced. "High pitched whistles" in video and TV hardware are usually harbingers of bad news.

hi ,,two things 1- water pump. but most likely check your pulleys they will make that high pitch noise one of them fixing to go bad and what will happen the belt will jam and jump lose and will lose all power ,,cause you have one belt for alt and the water pump mostly its the pulley right under the alt ,,hope this will help ....Joe

There may be a small hole or cut in a vacum line or possibly just loose. Also make sure the air filter box and the big hose to it are secure and clamps etc are tight. Pulleys and belts can make a high pitch sound also.
