Works by gravity, water entering from large downspout type pipe goes to smaller connection to product and water pressure pushes lid up to release water.

Horizontal Installation

Asked by Tom December 2, 2019
2
Answers

Yes, it can be installed horizontally, but the top retracts due to gravity - so it would not return to the closed position (if installed horizontally) unless you mechanically retract it. But if you are not concerned about that, it would work.

How do you install this? Just put it in the hole and press down with your foot? I did that but ...

Answers

If you have a problem with heavy rain kicking it out, I drilled a hole in the center stem and connected weight . No problem since. Even if it floods out, it stays close. You can also drill a hole in the side to create a pressure situation or into the PVC.

Yes, they are simple sitting in the pipe, there is no firm attachment. You can just pull it up and stick your hand right in the pipe to clear it.

Does the pop-up drain system come in 1-1/2 " pipe sizes?

I don't see one. You might be able to do an adaptor from 1.5 to 3" and use this. Here's an adaptor at THD that might work? https://www.homedepot.com/p/3-in-x-1-1-2-in-PVC-DWV-Reducing-Coupling-C4801HD3112/100343439

I just installed so don’t know how good these are for long term but looks good. It’s really pricey for just being a plastic emitter but I didn’t see any other alternatives.

I spoke to NDS, the manufactures after I could not find the pop-up emitter with a Spring, even though the description says that this model has a spring. I found out that model 420 has a spring, while model 420CW dos not (it uses a crimped pin). Home Depot calls this crimped model the 420C. Do not be fooled, It is harder for a lawn mower to suck-up the spring loaded version and break it, then it is to suck-up the 420 model. I wish Home Depot would go back to ordering the 420 model from NDS.

Works great and blends in well in the grass. Need to watch running over it with the lawnmower as it may pull the center up and break it.
