Comments: For its intended use, I'm sure this part is great. How could JG not be?However, it is NOT intended for the use that it appears most people are trying to use it for.I came by the website to look for something like this for an auto-topoff system. Doing a little more research elsewhere, I found John Guest's catalog, which specifically states that this bulkhead is not for submerged use. So, it's not designed to be at the bottom of a trashcan-reservoir for ATO purposes.

Comments: Good well thought out product. The only thing I found missing is a o-ring seal.

Comments: I drilled a 5/8 in. hole in the side of a 5 gallon bucket near the bottom and installed this in it,connected(with 1/4in. tubing like is used for RO/DI filters)to a Kent float valve in my sump for auto top off,I set the bucket on a table next to my sump for gravity flow,it works great.
<br />I did add 1.5 to 2 gallons a day,now I just fill the bucket every other day.
<br />My water level in my sump hasn't changed since I did this.
<br />I would have gave it a 5 star rating if it had came with a rubber gasket.

Comments: the part was fine just surprised it did not come with o rings or washers
