I ordered the mosquito blocking water tank flap valves, the 4" size. however these are larger than a 4" drainage pipe, by about 1/4 inch. Way too lose a fit. Had to use silicone sealer and a couple of screws to retain in place.

As for ordering on line everything was great. When I picked up the tank, however, it was NOT the tank that was shown on line..

Generally like the leaf guides. I have now purchased 7 units and about half have the screens pushed out when I unpack them. I think this is occurring in shipping compounded by the fact the screen is only held with a press fit - no glue. The coupling is packed on top of the screen and it appears to be pushing the screen out. So far I have been able to work it back in and glue it down. FYI - the screw that holds the cover - which is very easy to drop during the final stages of installation...never to be seen again...is a metric M4 x.7 12mm stainless if you have to replace it.

Was easy to install. I got the 3" to fit my existing plumbing does not hold as much water as I would like but is much better than not doing any pre-wash.

Curtis was very helpful in walking me through what equipment I needed and how to set it up.

Your third and sometime fourth party shipping protocol left me concerned and overly defensive about the protection of my product. The rain barrel is amazing, great product, don't get me wrong. Your companies release of all responsibility to damage during shipping gave me and I'm sure other customers anxiety. The barrel arrived just fine but I had to make extra notes on the driver's delivery slit to protect me as a customer because he requested I stop opening/removing the packaging to inspect for damage since he still legally owned the product till I signed off. I didn't want to sign off till I saw the product. Everything worked out in the end but had it not I wouldn't be giving my 4 star review.

Excellent products. I have the Leafeater and also the First Flush chambers on my downspouts. One part was missing from an ordered kit, and I am still waiting on getting that delivered so I can complete the installation. But for that delay, I would have given 5 star review.
