In terms of strength, this pipe would be at the bottom of the scale. However, the price is the most cost effective if there is no need for a sturdier choice of pipe. Due to its low wall strength this pipe is extremely flexible and typically comes in 100 ft coils. The most common application this pipe is used for is a French Drain which would be a perforated version of this pipe, but there are other uses for it as well. Such as retaining wall drainage, or on properties where there would be many turns in order to run the pipe to its final drain point, or ?daylight?. The flexibility allows for these turns without having to use many fittings like all of the previous pipes mentioned would. This saves installation labor as well as cost due to the lack of fittings needed
