This is what Makita claim,

"POWER : 6.5 CFM @ 90PSI; Powerful enough to run two framing nailers"

The loss of pressure indicates a leak, do you turn off the tap each day or leave the hose pressurized?

but it won't get drained of water...

Our climate is obviously very different to yours. In my business we used a compressor all day long, air was reticulated to each bench. The compressor had a label saying to drain the tank each. In the weeks after getting this compressor we opened the drain tap each day but not a drop came out. Even checking it around monthly, still nothing came out so we stopped the procedure. After retiring and leaving the business to my son which he closed after about three years when the cost of a new superior VCR was less than the cost of a major repair.
After it closed I was given the compressor and the first thing that I did was open the drain and STILL not a drop came out. Never in use did any water come out of the air drivers or blowers.

up grade...

About two years ago the tap on mine started to leak and I replaced it with one from Ebay that looks the same as the top right one in your picture. The photo above is taken from the thread "my shed now" some years old. It's too late tonight to have gone out and taken new shots.

CORRECTION...It's the same as the top LEFT one shown. It's an age thing confusing left and right!
