Can this product be reversed, to fit round downspout and square hole to drainage line?

Is this the same material (plastic) as the flexible black 3 or 4" PVC pipe?

The flexible PVC pipe is usually 10'-12' long and can be used to connect to a downspout
Asked by: JW
It may be a bit thinner but very similar.

Does this fit 4" PVC Sewer and Drain pipe which is different from 4" regular PVC pipe? If not, which connector or adapter could you use if any?

Example: I have looked at the manual and can't figure out what I did wrong.
Asked by: Wend
Thanks for your question. This item is not meant to fit 4" PVC sewer and drain pipe and we do not have any connectors that you would be able to use to do so.

Can this be easily fitted to regular 4-inch PVC pipe? And how would you recommend sealing such a connection?
Asked by: genkibrady
Thanks for your question. The end of the Flex Grate should fit into the 4" PVC pipe with no problem. If you feel you need to seal it, you could use caulk.

Flex Grate Downspout Filter is rated 4.0 out of 5 by 49.

Reading another review about rain water coming down the gutter downspout and leaking out past the screen grate...I too had same problem during hard rains so I added a sheet metal cover that could be lifted upwards to access the grate area and remove any trash. I could also close the cover to prevent any water being discharged. I've attached two pictures that show the cover. I also installed a lanyard to prevent the plastic grading from accidently falling into the 4" drain system I had installed. The grate sets on a plastic lip and can come loose. The water diverter under the downspout adapter was not my best work. Its kind of hard to cut plastic so I used some caulk and black duct tape to dress it up. As of now I'm waiting for a hard rain for a real test and that may come soon.

This is the best product, i used the gutter filters and they just clogged my gutters, this product really works. I took the filter and added an extras screen by adding a thin mesh, i tied it on using fishing wire. Now it filters the smallest of leaves. I have 3 of these installed and I have 2 as backups incase these are not sold anymore. I love this product.

The leaves and other debris don't always come out 100%, so after the rain you may want to check it to keep the drain clear for next time. I only have a single one installed so I can recommend this product.

They were easy to install and seem very durable. It's disappointing that they don't have other colors available (wanted white but couldn't find them available anywhere). Function-wise, I'm thoroughly impressed.

Rated 4 out of 5 by from Great product but needs small redesign Great product to keep underground drain pipe free of leaves. BUT needs a small improvement which I made with a pocket knife. The lower edge of the deflector shoot is held in place with the outside frame. This creates a small dam which does prevent small leaves from fall out. By cutting away most of the lower edge, it allows leaves to fall freely out.

Rated 3 out of 5 by from Good for some applications The produce is well made and fits very well both the large and small downspouts. I installed them on four downspouts. Because I have a lot of trouble with leaves and debris clogging my gutters, I thought I would install these and forgo the screens on the gutters. The leaves do wash down and most are washed out the opening but enough stick in there that a lot of water splashes out. They need to be cleaned out after every rain to keep them clear. I cut the lip off the bottom of one of them and the water actually runs out of that one so I don't advise doing that. Bottom line is they do work but if you are concerned about water leaking out around your foundation, they are probably not advisable.

Rated 4 out of 5 by from Works fairly well Did what it was supposed to during a recent thunderstorm. The storm dumped 2 1/2 inches of water with lots of high wind. The filter kept out leaves and larger debris as expected. Smaller stuff such as shingle grit and dirt passed through to our secondary screen at the entrance to our rain barrels. We've only owned this a couple weeks, so I can't comment on how well it will hold up.
