is there a big difference between the 1/4 inch and 3/8 inch basic system? i can't figure out which one to buy

the difference is the water supply line, which is 1/4 inch or 3/8 inch. The 3/8 inch is the larger of the two, if you expand the system adding a second misting line, the 3/8 would give you more water.

Buy the larger system as water pressure will always vary, and I'd rather err on the high side than the lower. It's almost impossible to keep the pressure consistent and very easy to blow out the fittings...unless you purchase a water pressure regulator. Then it really doesn't matter whether you use the larger or smaller hose...

Actually, the larger size moves more water to the misters and would allow more pressure at the mister end and if the misters are larger then more spray. Whether more mist creates more cool is debatable and even on that note, suggestion is to buy the larger size.

The Eight Inch Set Will Work The Best.....If You Nee A Greater Cutting Depth.....But They Both Will Work Just Fine For Normal Use....

1 inch... but you etter check how progressive might have changed things from the 2009-2013 series to the new 2014-15 series ultra. the former, was 1 inch. if you are not a big guy like me i'd maybe try the 400 series but again call progressive and then shen when you have your answer. rich

Depth is the only difference. I would try to use a 2x6 wall if at all possible. 3" abs just does not fit in a 2x4 wall with any structural integrity.

I'm sure the 3 inch would be fine, I have the 2 1/2 in. I like it very much.

No, but you can get an adapter to convert the 1/4" to 3.5" for just a few dollars.

It works fine on my hundred.But I still would suggest the four inch, it would be easier to use.

Strictly speaking as an amateur: 3/4" pipe is fine for an average household fun. Be sure to use the gas-type pipe thread tape or liquid sealer, and check for leaks. Believe the unit comes with a standard 110VAC plug, and that is low amperage. Unit works like a champ and the Takagi folks I communicated with were very helpful. Be sure the exhaust vents properly so that you have no (odorless) CO accumulation!

I own a 4.5 inch and I love it. Sorry I don't know what a #3 or #4 look like, on the bottom of mine is a #2.

I would imagine it depends on how deeply you plan to clean out. I just do a simple, quick clean and the 1.8 is more than I need.

The 3 inch would be good but you might want to get the 4 just to ensure comfort.

Standard sizes from 1/4 up to 1/2 inch. 1/4, 9/32??? 5/16, 3/8, 7/16, 1/2 and obviously I'm missing one. It's smaller than the 1/4, maybe it's 3/16. I've almost never used that, or the 9/32.

Avoid the 12 inch st all costs to firm. The 8 inch is much better. The warranty is pointless by the way

Hi Randy, The 3/16"-1/2"(six step drill) and the 1/8"-1/2"(thirteen step drill) both have 1/4" shank. The 1/4"-3/4"(nine step drill) has a 3/8" shank. Hope this will help you?

I am not aware of a 3/4 that you can buy separately. This unit comes with both a 1.5 and 1 inch barrel.

I would think it would depend how much "depth" of the 4" surface there is before the transition to 3". If you have approximately 2" of 4" diameter depth I would recommend the 4" product. The reason being that the device is installed by manually turning 4 screws to expand it into location. The "deeper" your location may provide a more complex installation in my "opinion".

Both are good, it just depends on what your socket sizes are. I own the 3/8 with a 3/8 impact set and it's quite powerful on it's own. The 3/8 is all around a versatile tool that will get most, if not all, of your tasks done.
