I had a plumbing company replace an outdoor sill cock that had froze. They replaced it with a Woodford model 17. I now have considerably less water pressure than I had before they replaced it. My other outdoor faucet has great pressure as do the rest of the faucets inside the house. They came up to trouble shoot it the other day and were not able to figure out why it is doing this. They spent several hours at my house replacing the sill cock and they also dismantled the sipon to see if that made any difference in pressure. It made none. They also blew through the sill cock after they took it out and there was no air that came out. At that point they thought that the sill cock was faulty, but then ruled that out after they blew through the new one which also had no air coming out.
I have several questions:
1. Any ideas on what could cause the lose of water pressure in the new sill cock when the water pressure is fine in the rest of the house?
2. Before I had them come back to my house, I asked them if their work was warranted and wanted to make sure that I wasn't going to be charged to have them come up. They said their work is warranted and I wouldn't be charged. When they left, they said they were probably going to charge me for their time. What can I do about this?
Thanks for all your help,
