Oxford plumbing, I believe, needs to review how they convey information to their customers as I am very displeased with this situation. Upon an initial call about my Culligan water softener dripping at the valve where water can be switched from hard to soft if needed. I was informed they would send somebody out the next day ,which they did. The plumbers (Ashley and an assistant) arrived around 4:30pm. When I told them it was a Culligan unit they mentioned they don't usually service Culligan and asked if I was told this over the phone, I told them I wasn't told this when I scheduled a service call for them to come. Anyways, they came in a looked at the unit and proceeded to write down the model number of the softener. I was told they have a fellow, John, who has a connection with Culligan and it's possible he could order parts. I wish I knew from the initial call I made to Oxford plumbing, that they don't service culligan rather than find this out when the plumber arrived at my house and be billed for a service call in which they only wrote down a model number for the unit. If I knew this I would have looked online for the part or called Culligan myself. Now I ended up taking the valve off and removing 2 O-rings the next day which I took to Home Depot. I explained everything to them and was told new orings will work as long as they are the same size because an "Oring is an "Oring" I ended up purchasing the orings and putting my softener valve back together and that fixed the issue with the drip. Pretty simple fix really. In fact I took it apart before this and couldn't figure out the problem at first. Then I realized the Orings make the seal.prpblem fixed. I never bothered to call John about a replacement part as it wasn't needed. All in all, I paid for the "service call" they did. Also took just over a month to recieve a bill from them which was a shock. I am still displeased with them and their services and will not be using them again as they should be more clear from the get go. I should have been told they don't service Culligan over the phone, which I wasn't.There was no attempt to even open the unit and take a look at what could have been wrong. Marc emailed me today as I paid for service with PayPal and left an email along with my payment. He stated they have protocol and can't use parts not made for that piece of equipment and that if an off the shelf o-ring failed who's fault would it be? How can you know if you don't check where it's leaking and whats inside. If I hadn't mentioned o-rings they wouldn't have known this is what was the cause because nobody else checked. So I decided to call my cousin after I finished work, who has been a plumber for 15+ years but lives an hour away from me, otherwise I'd have him come out. He himself said two O-rings that are the same size, thickness, type etc will work and that companies do these type of "protocols" to save themselves as it's business. He at least would have opened the softener to see what he was dealing with. Oxford plumbing did great service for us before which is why I called them. I also left a voice message with them and did not recieve a call back either. This is Poor service with no apology from a company that is supposed to be a reputable one.
