Looking for a local plumber to replace 2 gate valves with 2 ball valves. I've already received some ballpark estimates from local plumbing services and although I recognize the importance of skilled trades, the quotes, based on my engineering background, come to about $1,000 an hour! That's not going to happen. These valves are in an unobstructed area of the basement and guessing a half hour work for someone who knows what they're doing. I will procure the permit and arrange for the curbside main shutoff. If interested in doing this at a reasonable price for cash, let me know. Thanks.
