Ok... There is some serious issues with this device that I cannot find any information on related to back siphonage. I googled around some and couldn't find the info regarding safety protections required for this type of device. A vacuum breaker would probably work but because this is considered a chemical in the plumbing world this device shouldn't be connected to a garden hose which is connected to your potable water supply without a reduced pressure backflow preventer protecting the potable water within the household. I highly recommend massdrop DROP this product entirely and never sell it again.
By supporting this device you as a retailer vouch for it's safety which would be completely illegal in Canada. No store in Canada would legally be allowed to put this device on the shelf which is why they are trying to sell it online. As far as I know any device connected to potable water must be CSA approved. I could easily sue Massdrop if someone in my household got sick or died from said device. You can't guarantee that the required safety devices are installed on the owners house and I can't see any safety listed on the device thus it is a safety hazard.
I highly recommend everyone avoid this product for safety reasons. If there is a pressure drop on the house hold side of the potable water system while the device is connected but not in use it is possible for the chemical to be siphoned into the house. There is zero safety information that I could find regarding this device.
But please correct me if I am wrong as I couldn't find the info needed to prove me wrong.
Lastly if anyone in my city was caught using this they would be fined 5000 dollars. Our storm system is separate from the sewer system and as such the storm water is slightly filtered and used to irrigate crops. Pumping chemicals into the storm system is illegal here.
I'm not sure you are correct. There would be no problem with back siphoning unless somehow your hose no longer worked. There's really no way the chemical in this could get up your garden hose and then up into your house unless you had some sort of weird off the grid type plumbing system that was pumped from a storage tank.
If your storm and sewer systems were different, then no one would be able to wash their cars in the street.
And no, you can't sue massdrop for purchasing a product you know (or think) is illegal. It's your job as a citizen to know what is and isn't lawful for you to own.
There is nothing saying this device is CSA approved at least I can't find anything which essentially makes it illegal. So yes I could absolutely sue massdrop. They should be contacting their lawyers about this asap to confirm. As soon as you connect any device that holds any kind of chemical that mixes with the potable water supply safety measures are required. By law. Period. Every house should at least have a vacuum breaker system installed either on the outlet of the Hose bib connection or built into the hose bib itself. Since Massdrop or the product supplier cannot ensure this safety device(s) is installed at the point of use or evn warn the purchaser that this is required than Massdrop and manufacturer take responsibility for said product. Further steps are required to protect the potable water system if say a commercial dishwasher has a chemical mixing / soap dispensary system that mixes with water. Like an RP.
Follow me for a minute on this: If for example the device became faulty, being dropped, damaged, or simply not built correctly and there was a house on fire in the same neighborhood close by the massive pressure drop caused by fighting fires basically siphons water out of every nearby house. Water flows to the lowest pressure point. Thus if this device or any part of the connection was faulty in any way it is possible to suck the chemical back into the house. Which would mix with the potable water which you drink and your kids drink.
So if you read the paragraph above is why I posted originally. I see nothing that states there is any kind of safety measures built into this device or anything stating it is CSA approved. This is a required feature with ANY device that is connected to a potable water system. This is the law.
And finally yes our systems are separate and nobody is allowed to wash a car in their driveway or on the street unless it is just water. BTW i scored 98% on water treatment on my final exam.
It's not a Canadian law, it is by municipality. I have found nothing to support your claim it is a Canada wide law. There are plenty of cities that don't allow it, same as in the US...but it is by complaint only, there is no water police.
I'm assuming it is a venturi system, which means if there is back siphoning it'll just pull air and not soap.
Unless you can provide me with the Canadian law this is breaking, I'll have have to assume that you don't know what you are talking about.
Sure bud assume anything ya want. There isn't a single retailer in Canada allowed to sell anything that connects to potable water that doesn't have a CSA stamp right on it. There also isn't a single American supplier allowed to sell items in Canada without the very same stamp. Every single plumbing item sold from the states into Canada requires CSA. Period... there is no getting around this bud. Zero fucking chance. Any device like this would at the very least have a vacuum breaker but any chemical system connected to DRINKING WATER must have for-mentioned protections on the device. End of argument. I have the tickets that prove that I know what I'm talking about and passed all the tests. Knowing what I know... i would never connect this device to my drinking water.
These rules have been put in place for a very long time in case something unforeseen happens (which normally it already has) to protect the water supply.
Go educate yourself before assuming the guy with the tickets doesn't know what he's talking about. https://bcwwa.org/ccc.html
Does that mean if for some reason my hose was in a puddle of piss and there was a pressure drop in the house, my hose would suck up piss?
This guys a fuckin Nutter....
Actually he has a point. I have a backflow preventer on the spigot on the outside of my house. As an example, if you had your hose laying in a pool that was foul, the fire dept hooks up to a hydrant down the road, they drop the pressure on the municiple water supply with their draw. Without a backflow preventer, your foul pool water will get drawn into your house and possibly even into the public water lines in the street. The situations where this can occur are limited but with so many people connected to the water system, the chances aren't as small as you think.
