Connecting the irrigation hose
The irrigation system of the summer cottage is an important element of the improvement of the cottage. By organizing a good irrigation system, you can significantly save your own time and effort.
In most cases, especially in old dachas, the irrigation system is organized using hoses. Those. there is a central water supply, to which hoses for irrigation are connected. The main problem in this case is the connection of hoses to the central water supply, this applies to both modern type hoses and traditional rubber armored hoses.
The problem lies in the fact that, as a rule, country water supply is made of metal pipes. In addition, in old dachas, various home-made adapters are screwed onto these bends, which do not fit in diameter, both for new hoses and for traditional rubber ones.
Fig.1.
In addition, a big problem is that it is often very difficult to unscrew these adapters. From this moment, the main work begins on connecting the hose to the country water supply.
There are several ways to expand a stuck thread.
- Tap on it with a hammer from different sides. This method works well for non-old threaded connections, i.e. which are only a few years old.
- You can use a gas burner and warm up the threaded connection. But there is a drawback, you must have a gas burner or a blowtorch.
- There is also a universal way to cut off the adapter. To do this, the grinder makes several cuts, after which the adapter is easily removed from the outlet.
Fig.2.
Here you should pay attention that first a transverse incision is made to make the adapter as short as possible, and then several longitudinal ones. When making an incision, care must be taken not to cut through it and cut the thread, so as not to spoil the bend.
Fig.3.
After the cuts are ready with a chisel or a conventional screwdriver, the adapter is removed from the outlet.
During all these operations, it is important that water does not flow from the pipe. She can get on the grinder, which is fraught with electric shock.
Fig.4.
As you can see from the photo, everything turned out to be done quite neatly without damaging the outlet. Now you need to screw on the tap and connect the hose for irrigation. Why did you decide to install a new faucet? The fact is that although the old crane holds, it does not have a lamb and it is very tight. It is not possible to replace it with a new one, because. it is not possible to unscrew it for the reason described above, and it cannot be cut off, because pressurized plumbing system. Therefore, it was decided to simply screw on a new tap, and replace this one in the fall, when the water will be turned off.
At this stage, the following problem arises. The new tap will not screw on the old thread. The fact is that the thread is partially rotten, partially contaminated. The solution to this problem is simple, you need to "drive" the old thread. To do this, it is convenient to use a special tool for cutting pipe threads.
Fig.5.
In general, cutting pipe threads is quite problematic, especially without a special tool. In this case, the device is homemade, made according to sketches from a pipe threading tool. It is desirable to have such a tool at hand in a summer cottage, it often helps out in such situations.
If there is no special tool at hand, then cutting the thread is very problematic, but updating the old thread is not difficult. You can use a plate. You can also try to remove rust with a wire brush and WD 40. WD 40 softens rust well.
Fig.6.
In this case, I used WD 40 as a threading lubricant.
This is what a homemade pipe threading tool looks like.

After the thread is cut, it is necessary to wind up and screw on the tap. Traditionally, winding is done with flax. In this case, the winding was done with a fuma tape. Firstly, flax was simply not at hand. Secondly, over time, flax absorbs rust and becomes, as it were, a single whole with a threaded connection. As a result, in the future, if necessary, it will be problematic to unscrew this valve.
Fuma tape, unlike linen, does not absorb water and rust and does not "grow" with the thread. Therefore, removing the tap if necessary will not be a problem, for example, for the winter. In addition, given the low pressure in the country water supply system, the fuma tape will perfectly cope with leaks.
Fig.8.
So, we wind the fuma tape on the thread in one layer. This is enough to create a tight connection. I start winding the fuma tape from the beginning of the thread clockwise, because. the faucet will also turn clockwise. This winding direction will not allow it to wrinkle or move, which is very important for the tightness of the threaded connection.
Fig.9.
The winding is ready and you can screw on the crane.
Fig.10.
The crane with a little effort is screwed on by hand. And put in a comfortable position. For reliability, it can be slightly tightened with a key. In general, water taps should not be tightened too much. Tightening force does not affect tightness. The tightness is affected by the density of the winding.
If the water tap is pulled over, then, firstly, it may burst, and secondly, it will be difficult to turn it off in the future. Therefore, if during the installation of the tap a non-tightness of the threaded connection is detected, then it is necessary to remove the tap and make a tighter winding, and not try to tighten it more.
Fig.11.
Now you can proceed to connect the hose for irrigation. I purchased a rubber armored hose for irrigation. Why my choice fell on this type of hose I will tell at the end of the article.
The main criterion for connection is simplicity, both connection and disconnection. For these purposes, a split fitting for a polypropylene pipe was chosen, complete with an adapter for an inch thread, like a tap. The thickness of the outlet of the polypropylene fitting is 20 mm, which is exactly equal to the inner diameter of the hose. Tighten the adapter well
The convenience of using this type of fitting lies in the fact that to connect the hose to the water supply, it is enough to screw only the nut on the fitting. If you use a non-detachable fitting, then you will have to twist the entire hose when connecting, which is very inconvenient.
Fig.15.
Given the low pressure in the country water supply, the fitting nut can be tightened simply by hand without resorting to a wrench. The main thing is not to forget to install the gasket.
In conclusion, as I said a few words earlier, why an ordinary rubber hose was chosen, and not a modern one. The fact is that, even though the rubber hose is less convenient to use, it is heavier, it has a larger diameter compared to a modern hose of a similar cost. Accordingly, the flow of water through such a hose will be greater. This is true at low pressure in the system. As a result, using a rubber hose for watering, watering itself is carried out much faster.
