Which pipes are best suited for feeding a deep well into two towers?

Hello! Up to 50 m, you can use plastic with a diameter of 12.5 cm. These pipes are lightweight, inexpensive, easy to install, do not rust. Plastic is cheaper, but since you have a decent depth, it is quite possible in 10 years there will be problems.

Steel pipes are still stronger and more reliable, but significantly more expensive. Manufacturers claim that a pipe made of high-quality black steel will last at least 50 years. The wall thickness of such a pipe is 0.6 cm, the diameter must be selected according to the appropriate parameter of the pump, usually 13.3 - 15.2 cm. Soil movements on steel pipes affect, but not significantly.

It is believed that steel pipes are inferior to plastic because they are susceptible to corrosion. Rust will indeed appear, but in the distant future, in 20 to 30 years, even then in an amount not so critical that the filter does not filter it.

If you are ready to spend a substantial amount, you can take alloyed stainless pipes. The best option is to rent a brand of at least 10 G2. Appearance on the attached photo. Alloyed steel will give the opportunity for conservation of the well for a very long time. The advantage of a quality pipe is the prospect of its operation in a wide range of pressures - from 6 to 10 atm. Plastic can withstand only 2 atm.

In any case, the pipe must be pressure, only this type of pipe is able to withstand pressure both internal and external. Here in this article on our website the question of the choice of pipes is well covered and their comparative characteristics are given.
