"Never shorten the tubing to repair the hose": there is a safer way
Usually, even with a normal crane, there is a complete set of parts of dubious quality, so the manufacturer competes with the price for our choice. He is not guilty, the market decided so, capitalism is that.
Hose repair
First of all, the shower hose leaks, the family looks at the head with hope, if the owner is experienced, he solves the problem in five minutes.
He knows that the reason is in the broken pipe, removes the fitting, cuts out the damaged area, puts it back in place, and demonstrates it to the household. The result is one hundred percent, and the reputation is high. You recognize yourself, no, but I found out. This is a temporary solution, besides, the tube is shortened, withsoon the problem will recur.
Reliable way
Some will say, oh well, you just need to buy a new hose, but it will also have a white, unreliable tube. It needs to be replaced!
I bought mine on the market for other purposes, but it came up, there is still silicone, they better in parameters.
In any case, these pipes will solve the problem for a long time, they are much more reliable, they do not collapse like factory ones, it remains to measure the length of the hose and buy with a margin.
Replacing in time is a little longer, since two fittings must be removed.
I put it in a braid, cut off the excess, put the fittings in place, installed and forgot about the problem. The only negative, after a while they will forget about it and household members will think that the hose is just of high quality.
