Water starts to spray from the bottom of my Bosch Aquatak 120i when i turn the water on. Is it still safe to use when this is happening


Electricity and water can be a hazard which could be life threatening, but you can operate electrical equipment in a wet environment if you are careful and follow safety precautions. Most import, make sure the electrical outlet you are using for the pressure washer has a working ground plug. Just because an outlet has three prongs does not mean the ground is working. You need to use an outlet tester which is inexpensive from a hardware store or use a multi meter to test the ground for conductivity to earth ground. Your power washer should have a working GFI (Ground fault interrupter), and you need to press the test button to make sure it is working. If your power washer does not have a GFI purchase one from a hardware store. I would also plug the power washer directly into the electrical outlet since an extension cord could have a bad ground connection and will cause the power washer to pull more current from the outlet. Make sure the power washer is raised of the ground so it will not sit in a pool of water. If you follow the safety precautions you should be safe but keep in mind water does not carry the electrical current, it is the impurities in the water which carry the current. Therefore, water could be more conductive depending on the impurity of water. However, it sounds like a loose connection in the power washer which could also be an o-ring or a washer is broken and it would b a good idea to have it fixed.

I am getting a lot of distortion feedback when I connect my computer to the mixer but the feedback only starts when the computer is connected to an electrical outlet. I have plugged the computer to a separate outlet but I am still getting the feedback. The system plays fine on the battery from the computer but as soon as the computer is plugged into an outlet I get terrible distortion.


Sounds like a ground problem. Try to hook a ground strap or wire from the case of the computers power supply to the ground of the mixer. If it still has noise, try to touch the ground to the bracket of the computers sound card. Most likely, the computer uses a three prong adaptor and the mixer does not. Outlet grounds have voltages which bleed off from motors and other devices, which could cause the 60hz noise. If your mixer has a three prong plug do not plug your computer and mixer in separate outlets with separate grounds or you could fry your system. If you still have problems use a three to two prong adaptor and attach an isolated ground wire on the adaptor for the computer.

No power in the two bathroom electric outlets.


What do you mean protected, if they where ground fault they have a test button,or the breaker
can be a ground fault, but it is a lot cheaper to buy the outlets. Call someone that knows electric,
because you need to check to see which outlet has power coming from the breaker,because this one
is probably bad, which will not allow any power continue on to the next outlet. Just say you were
going to do this yourself , you need a tester to make sure power is coming to the outlet.

You could buy a ground fault outlet and a regular outlet, but you have to make sure that the ground fault
is wired from the breaker, the power from the breaker, then the wire that Leeds from the ground fault
to the other outlet will also be protected, one ground fault can protect two other outlets that are connected to it in what is called a series. Unless you have a multimeter to test what needs to be tested
you should ask someone that knows electric. If you have any more questions please post back as everyone is more than happy to help. I don't feel comfortable trying to explain to you how to replace
the outlets, it can be dangerous and I would not want you to get hurt just to save a few dollars.
