I haven't come across that type of product before. My only concern with placing something like that over the grate is if the pit also serves as a surface water collection device. You would basically block all water from draining into the pit. This likely wouldn't be an issue most of the time, but in a torrential downpour, you would probably end up with a new pond feature in your backyard.

Worst case scenario, say you lay a slab over the area and build a shed. If the council needs to perform emergency works and needs access to the easement to fix the stormwater, then I suspect that the shed and slab will need to be removed very quickly and at the homeowners cost.

Northern neighbour has grass growing over his next to a weather vane. Maybe I should stop typing and start building an Ark?

American Society of Sanitary Engineers publishes product standards of safety for plumbing systems.  There are 5 major standards for mixing hot and cold water.  Four of these standards are mentioned specifically in both the IPC and UPC Plumbing codes as well as the four states that use their own codes (California, Illinois, Wisconsin, and New Jersey).  Commercial building require ASSE certified valves. Click below to understand how and when to use these valves. As always, you may contact a Leonard Sales/Engineering Specialist for assistance.

Unfortunately, you can't lay grass over the stormwater or have anything permanent in place. You'll need to see if there is an access easement on your property plans. Not only is this drain an access point for the stormwater for maintenance, but it also looks to collect water in your backyard. By permanently covering it, you risk flooding the area or inhibiting maintenance crews from accessing it.

Can we flip it over? On the one that was left with me the grills are now lower than the top edge. Would this now be the best spot to lay our fake grass - which would now be level with your lawn?

Don't shoot the messenger, but below is a photo of a storm drain, well, sorta. It belongs to an 80 year old lady whose property adjoins my backyard.

The pit has been installed sunken quite deep into the ground, and this alludes to the fact that it could be placed there not only as an access point but also to collect the runoff from the surrounding area. What's on the other side of the fence? If it were an apartment block, this grate would no doubt be placed like that to capture water running under the fence.

Council went through our properties with a similar drainage network as described above which wormed its way though backyards. She told me one day she didn't like it so she placed shopping bags (when they were plastic) over the 'vents' and shoveled dirt on top. I lent over the fence for this shot just now and noticed a fern successfully growing.

Welcome to the Bunnings Workshop community @SueGillan. It's terrific to have you join us, and many thanks for your question about hiding a stormwater drain.You might like to have a read through these previous topics on the subject:

It really depends on what the drain is for. If it's a drain pit that was installed by the property owner, then it's entirely up to them if they want to cover it. If it is an access point for the council stormwater, then technically, you shouldn't be covering it and certainly not with anything permanent that would prevent access. If it's for council access, then you'll likely find an easement on your property plans available through the local council. If there is an easement, then you shouldn't be building anything permanent over the drain or the pipework that runs through the property and that easement. Council advisors will be much more versed in this, so I'd advise contacting them.

They certainly weren't installed by the owners. In fact council intended to put one in my backyard but I had a small shed not indicated on their plans. But they left the grill. Dunno why.

Before you consider any work, you should check your house plans and chat with your local council to find out what restrictions will apply.

Every building is different and all manufacturers of mixing valves pipe recirculation uniquely. We have a video to help explain the basic design of a tempered recirculation system with a Master Mixer. This video will help the plumbing professional select the proper piping method for the job.
