I think air compressors with dual tanks are impressive looking tools. But I don't understand why they are better than a compressor with one big tank. The only air compressor I own has one big tank. The directions say to open the drain valve (with its very disagreeable and typical tiny t-handle) after you finish using the machine.
Why have dual tanks on an air compressor?
Must we drain both tanks on a dual tank compressor?
Who sells a valve that will replace those tiny t-handle valves and be comfortable to use?
