I called Bonfi and told them exactly the part I needed for my boiler. They would not quote a replacement over the phone. I had to pay $89 to have a tech come out and quote the job. Tech came out and quoted $1288 to replace the valve which retails for $274. Outrageous! We both agreed the job would take about an hour. I paid the $89 and kicked the, out of my house. I feel sorry for anyone who calls these people that does not do their homework first. They are ripoff artists!
