Great Price and Product with All up and running and working well with a few issues. Biggest issue was no air or water coming out of the air bleeder valve which built up a large air pressure in the tank such that when pump was turned off it would push a large amount of air back into the pump. After a day of trying to figure it out, with much Googling, it ended up the cartridge on the top of the internal air bleeder pipe was not attached and, in the coiled lid spring, would pop up under pressure and block the top hole where the air is supposed to bleed out of. After removing the cartridge, and some stress in dealing with this, all is now working as it should.
Very little on-line instructions were mainly okay but it was not clear where the 2 O rings go on the Union and the on-line Expanded Diagram does not show them correctly with one shown between the threaded part of the Union and the main Filter Body. However, with 2 O ring slots on internal side of the Union piece that you bond the eternal 2 inch PVC pipe to, I was fortunately able to figure that out correctly too.
Last but not least, probably also jostled in shipping like the loose Air Bleeder Cartridge, the top round plastic on 1 of the 4 filter elements was cracked. After all that though, I'm very pleased with the filter design, operation, price, apparent durability and appearance. Solid with no leaks.
My hope is that Vevor, on reading this, will send me a replacement filter cartridge, will improve their Instructions and also provide a direct access to a website for procurement of any parts that may be needed in the future, so they can be replaced quickly and easily, for ALL of us otherwise very Happy Customers.
