That stinks Fran. Our temps have been all over the place the last week or so. It was 61 when I left this morning and it's supposed to get into the 70's but rain is in the forecast.
Last fall I had a leak in a pvc fitting for my sprinkler system where it first comes out of the house and goes down into the ground. I fixed it and thought I was good. Then the other day I turned the water back on to run the sprinklers and the next day I noticed the sump pump running more than normal. Evidently there is another leak on the same pipe but this time it's under the ground so I'm going to have to dig it out to fix it as soon as we can get more than a couple days of dry weather in a row.
