How often should RPZ valves be tested and serviced?

RPZ valves should be tested and serviced annually to ensure they function properly and meet regulatory requirements. However, in some cases, local regulations or the specific application may dictate more frequent testing intervals. Regular testing helps identify any issues or malfunctions promptly, ensuring the continued protection of the potable water supply from backflow contamination. Property owners should consult with qualified professionals familiar with local regulations to determine the appropriate testing frequency for their RPZ valves.

What are the signs that an RPZ valve may be malfunctioning?

Signs of a malfunctioning RPZ valve include: Discharge from Relief Valve : Water discharge or leaking from the relief valve indicates a pressure issue. Reduced Water Pressure : Decreased water pressure throughout the system may indicate a blockage or failure. Unusual Noises : Sounds such as hissing or banging within the valve assembly may suggest internal issues. Visible Damage or Corrosion : Physical damage or corrosion on the valve body may compromise its effectiveness. Regular testing can help identify these issues before they escalate.

I had pipes break and Austin called me back in a timely response. This was on a Sunday evening . Which is hard to get someone out. Austin evaluation of the problem and gave me options. He fixed the problem in no time and hauled away all the old c cvc pipe. It had become brittle and broke real easy.

Boston Williams, the Plumbing Technician, had to redesign the plumbing for our kitchen and even after running into unexpected problems with the pipes in the wall, he did an excellent job. He made the pipes more efficient, saved space under the sink and was a very pleasant person to work with. Excellent job.

Had such a great experience getting our air ducts cleaned before winter! We moved into our home over the summer after the same residents had lived in it for 50+ years and it was built in 1902. So we’re going through all our firsts. The gentleman who came was super helpful explaining everything and told us it probably hadn’t been done in 60+ years. Will be returning to Lanz next time we need this work done!!

From the initial contact and service call through the visit and quote for a new furnace, Lanz representatives have been courteous and helpful. There is no hard selling; they walk you through the process and answer all questions and concerns. I couldn’t recommend Lanz more highly.

I think LANZ does a good job with plumbing, and I know inflation is terrible, but I was charged $452 for 20 minutes of work on my kitchen leaking pipes (vent repair). That seems way over priced!

We got a mini split heating and air conditioning unit from Lanz inc. Everyone I dealt with was very professional and kept me well informed every step of the way. It was a great experience and I will gladly recommend them. Above and beyond expectations.

I called them with an emergency plumbing problem at noon on Saturday. Dirty water was backing up into our basement toilet and shower. I knew that meant the sewer line out to the city sewer was clogged. He came to the house within an hour. The plumber rodded out the line and fixed our problem. He saved us from a plumbing nightmare! Then on Monday a senior plumber went back to the house to double check the sewer line. Excellent service!

Friday morning we woke up to no hot water. The water heater was not working. It's electric and it had power to it so I knew it was the heating element or the thermostat. I called land and they had a technician out at 4 that afternoon to diagnos the problem. The water heater needed to be drained and that takes time so the technician left to get the parts it needed and came back on Saturday to fix the problem. If you need good affordable plumber service call Lanz plumbing Heating and ac. You won't be disappointed.

He also pointed out a separate issue we weren't aware of. We'll definitely be calling Lanz again based on the great customer service experience we had with Shannon.

Boston was so professional and polite. He explained everything he did and showed before and after pictures. He was actually early (Boston called first to verify it would be okay with us) Their prices are very fair and they are timely in coming out. Additionally, he had necessary parts on the truck so he could do repairs on the spot. I Love this company!

Linda Jent

16:06 30 Aug 24

Shannon arrived on time. He was very professional and informed us right away what the cost would be, before he started to work. He worked very hard to locate the laterals and the second hatch off the septic tank. He had to dig through rock and did not complain at all. When he found a problem he kept us informed at all times and answered all questions. He tried another cutting rooter when the first wouldn’t go through to at least give us a way to temporarily fix the problem. I did not feel as if he was trying to trick us or add costly repairs that we didn’t need. I would highly recommend Lanz and their tech Shannon. Thank you!

Jada Burr

My daughter already uses Lanz and recommended them to my son when he moved to the area. He was busy so I scheduled the appointment and was present during the service call. Not only did they come for service the same morning I called but Matthew and the tech in training who accompanied him were perfect. They covered their shoes before coming in, they got to work quickly and solved the problem even quicker. They were respectful, efficient, and didn’t try to sell a new unit but replaced the needed components for a very reasonable price. Matthew explained everything in detail and made sure I understood the problem and the solution. Perfect is the best way I can explain this experience.

I can’t express enough what a great and comprehensive job Michael Savage and his team at Lanz did for us when our AC went out over the weekend. Michael knew a heatwave was coming and came out on a Sunday evening to assess the situation and give us some options to review. While this wasn’t a planned expense for us, he made it easy to understand the options and gave us some flexible choices to make. On top of it all, Michael was able to find a way to get us an appointment later that same week for the installation to get completed before the big heatwave struck! We couldn’t be happier with the great customer service and professional work that Lanz did - we highly recommend them for any of your HVAC needs!

Richard Griffet

19:12 25 Aug 24

They just want to persuade you to get all new unit put in without fixing the problem and not 100% sure but I think he was draining my refrigerant as he was supposed to be checking the level to make it look like I had other issues with the unit

I recently had an exceptional experience with Lanz Plumbing and couldn't be happier with their service. Two plumbers from their team came to my home to address a serious issue with my sewer line that was being blocked by tree roots. From the moment they arrived, they were insanely respectful, transparent, and professional.They took the time to thoroughly explain what was going on, how they would fix it, and even offered me a maintenance plan that I gladly signed up for. Not only were they skilled and knowledgeable, but they were also personable and engaging, making what could have been a stressful situation much more pleasant.On top of their outstanding service, Lanz Plumbing was incredibly affordable, which was a huge relief. I highly recommend them to anyone in need of plumbing services. Trustworthy, friendly, and reasonably priced—Lanz Plumbing is simply the best!

We called around 7pm for a leaky toilet, Lanz had someone get in touch quickly and he was there by 9pm (finishing with a previous customer). Phillip was very kind and communicated everything along the way. He was conscious of his noise level since it was later in the evening & fixed everything by 10pm. I would use Lanz again, they saved us from a flooding bathroom!
