I recently used Neerings Plumbing, Air Conditioning & Heating for the first time. They installed two pop ups in my sinks. I was also having low pressure and I asked if the could put in a PRV to increase the pressure. The technician said yes, but they told me it would be $971. When I talked to another company, they said they could do it for only $265. So, I think they tend to be really overpriced. The pop ups they did were a little overpriced, but it wasn't bad. But, the service was great! They were on time and the technician was really friendly. He worked efficiently!
