I'm not really sure why, but the house I live in has awesome water pressure. It is great for washing the car or driveway off, as I don't really need a pressure washer. My shower faucets will hurt you if you turn them on full blast.
For the most part I love this, except for the fact that I can't leave my water hose turned on for very long until the hose ruptures. I have either split or blown the ends off of about 6 different hoses, but they have all been cheap looking hoses to me.
So who makes a hose that will stand up to this? I was thinking something canvas?
The house pressure is to high need to correct that otherwise you are spinning your wheels, a 30 dollar gage and 15 minuets of time will save you loads of$$$. You can adjust the house pressure, find the line where it enters the house you will find a valve that can be adjusted.
Here are some pictures of what you are looking for

Here is the tool you will need:

Here is a clip to show how:
It is a simple adjustment, the problem with all that house pressure is it can cause things like the toilet fill valve to not shut off. Can cause washing machine hoses to fail, never had that one, that would be a very costly mess. You already are seeing the outside hose rupturing and failing, the high pressure you like is the bad actor, not a weak hose. My house was 100 psi loved it but the house did not.
There is a pop off valve on the water heater that will fail start to leak water slowly and steady because of pressure, new valve will temporary fix it, but the problem will return. You are starting to see the down side of the water pressure being to high. The house internal pressure should be 40 - 50 psi max, feel free to check that spec, but I had 100 psi water pressure loved it, but was replacing to many of the items I described. Once I figured out what the problem was, lowered the pressure and all the problems went away..
Good luck but I would strongly suggest you have a look at the pressure, just get the gage put it on the hose or faucet turn it on you will have an answer instantly.
