I am looking to buy some garden hoses and I want to be sure they will be strong enough to use with a sprinkler, spray nozzle, or drip irrigation system if I buy one in the future.
My water pressure at the faucet is 50 PSI. I've read that your hose burst pressure should be 4 times the expected working pressure. So that would mean a burst pressure of 200 PSI. I also read that if you're going to use a garden hose with a nozzle or a sprinkler, you want a burst pressure of at least 350 PSI. But I can't find anywhere else on the Internet that talks about this, so I'm wondering if this second article is just making a overgeneralization since some places might have a high faucet pressure and so they just picked a high PSI number just to be safe rather than trying to explain to people the aforementioned 4:1 ratio.
So my question is - do you really need such a high hose burst pressure for a sprinkler or nozzle? For example, might a sprinkler actually increase the PSI exerted on the hose - thereby making the working pressure on the hose higher than 50 PSI even if the water pressure coming into the system was only 50 PSI? Like might there be some designs that exert some sort of backpressure that increases PSI on the system to increase the distance water sprays?
Thanks for any insight you can provide.
