What size air compressor should I purchase to blow out an inground pools water lines. Also to blow out an outside water line that runs under ground and approximately 70 feet slightly uphill to a water faucet used by the pool.
what size is the line
Any small one with a 3 to 5 gallon tank will do. You only have a couple of hundred cubic inches of tubing to fill and even a small compressor will give you all the pressure you need.
A regular wet/dry shop vac should do that.
Most anything will do. Since it doesn't have to hold pressure for long periods of time, a used one would suffice. Shop around. DO NOT buy an oilless. They are obnoxiously noisy and wear out quickly. You should be able to get a good used one pretty cheap.
