So, I had to drain my pool to get rid of some metal staining that just wasn't going away. My back wash dumps into my yard, which drains down hill into my neighbor's yard. Not good for good neighbors. So what to do? I bought the 2 inch back wash hose at lowes. I needed 150' of it, so I bought three of them. connected them together with 1.5" pvc pipe and hose clamps. It lasted about 5 minutes, then started springing leaks everywhere. I have to pump uphill to get to the street storm drain, so the hose has to take a little bit of pressure. My sons and I chased leaks for about 3 hours and then gave up, deciding to come up with a different solution. Being the electrical engineer by degree, I was determined to re-engineer this. So I gathered up the hose pieces that had split apart, shoved them in a trash bag, and off to lowes I went to get my money back. I was miffed at lowes, so I went over to Home Depot. While I was there I started searching the plumbing aisle for ideas. Then it dawned on me, garden hose fittings. 3 garden hoses will give me an equivalent volume of 1.5 diameter pvc pipe, or close enough to it. So I bought 3 pvc hose fittings, 3 1.5 x 3/4" x 1.5" T fittings, a 1.5" cap, and a ball valve. I had some 3/4 pipe and some 1.5 pipe at home. So this was the result:
I had plenty of garden hose laying around to make three 100' runs. So i bought some cheap 50' hose and completed the length for each hose to the street drain. Cranked up the pump and had the pool drained overnight. I plan on using this from now on to back wash. Hope this helps anybody else who doesn't want to spend $200 on discharge hoses if you have a long run to your drain point.
