Tank drains over a few days
(Calgary, Alberta, Canada)
Hi there. I have a de Walt D55167 Type 1 compressor. Once the compressor reaches its max. capacity, it shuts off and all is fine. Over a period of a few days (let's say 4 days, it loses about 20 psi. After a week, it loses another 50psi. Where would this leak be coming from? I've checked everything with soapy water at all the fittings...........I can't seem to find anything. Nothing is connected to the compressor. Thanks.
Hello Jack. Compressed air can be tricky. A pinhole leak might be very hard to find, yet over days, drain a tank to zero PSI.
You are draining the water from the tank daily, I hope.
If you have soap tested all possible exterior leak sites, then my guess is that your tank check valve might be a bit cruddy, and isn't seating completely. If it leaks, all the air will drain from your tank when the air compressor is off.
dewalt - a very high pitch noise
Produces a very high pitch noise while running, especially when
warming up! How can i stop this?
Boy Tom, that's hard to say. Is the noise coming from the motor or the pump?
Is the noise a squeal like metal on metal?
If it's oil lubed, you do have sufficient oil in the sump?
Any other DeWalt compressor owners experiencing the same noise?
