Pressure regulator cost?

With a service company it will usually come down to, what is it worth to you.There may be things about this job that make it so expensive maybe an expensive part or a long labored fix,after hours rates ,things like that. I would say for the most part plumbing is a trade that charges hourly not a flat rate fee so that $950 estimate does sound way high.I'm no plumber but i dint think it would take no more than a $250 regulator.(I'm guessing) so at $100 an hour,seems like a 7 hour job.I don't think that it should take 7 hours to change a regulator & 4 washers.I would call for a second opinion. I have a recomendation, I think this forum is local,neighbor, Plumbing By Kirk always takes care of us with fair rates and quality work and may come out for a free estimate.Give him a call (661) 263-6519 he probably services your area.
