Anderson Kantleak RV Water Service Panel Upgrade and Installation Guide

Anderson Brass Kantleak Water Service Panel

Recently, we were provided the opportunity to work with Anderson Brass Company by testing their improved RV water service panel. We replaced our existing plastic-fitting Anderson 200RV water service panel in our fifth wheel’s utility distribution center (UDC) with a better-engineered retrofit panel. Unlike the old plastic leaky and unreliable valve system, the Kantleak MANRV101-RF is manufactured with all brass fittings.

About Anderson Brass Company:

Anderson Brass Company is a family-owned business based in Hartsville, SC and has been in business since 1931. Built in 1982, their modern manufacturing facility features state of the art technology. They have been a primary provider of water service panels and selection valves for multiple RV manufacturers for many years.

How the Anderson Kantleak Water Service Panel Valve System Operates

The Kantleak panel has a knob in the UDC that rotates either left or right to allow us to select how water will be provided to our coach.

For example, we turn it to City when we are in a campground with a water hookup We turn it to Fill when we are adding freshwater to our RV’s onboard water tank. And, prior to winterizing our system for storage, we turn it to the specified Winterize, when we pump antifreeze into our RV’s water system. Or, we turn it to Normal, when we need to use the RV’s onboard water pump.

The Old RV Water Service Panel #200RV

The former Anderson Kantleak Water Service Panel we replaced was a #200RV which has a plastic main body with a rotating knob. It would click and lock into each position as we would rotate the knob.

The valve has an internal plastic core that relies on several rubber O-rings to maintain pressure and keep the valve functioning properly. It also has four positions for selection, but is not easy to read what position the knob is actually in.

Unfortunately, the former valve has been prone to failure; especially if the knob is rotated while under pressure. In the past, many RV owners would call Anderson Brass Company to seek guidance and instruction for a leaky valve. They would provide replacement cores if the valve failed. However, ABCO has manufactured a much better solution.

The Wave of the Future

Anderson Brass Company has recently redesigned and developed a much-improved version of the water service panel. The new retrofit panel that fits our 5th wheel, MANRV101RF  is simply amazing! This one will alleviate future valve issues or failures. We think it will revolutionize the RV industry for water selection valves.

The product’s construction and assembly is top notch. The new Anderson Valve is constructed with all brass components on the back of the housing panel. It features teflon seals to prevent leaks while ensuring a lifetime of reliable service.

The new Anderson Kantleak water service panel provides swiveling attachment points to provide strain relief for the water line connections. This will also aid in attaching the water lines to the valve’s main body with little to no resistance.  A well constructed brass check valve has been added to ensure water pressure is maintained and should help in eliminating unnecessary cycling of your water pump when dry camping.

Anderson Valve Company’s product developers have designed the new valve with three positions for the knob instead of the former’s four positions. The knob’s positions are now marked with easy-to-read lettering.

The much-improved Kantleak valve knob rotates smoothly unlike the old one. Just as important, it’s a direct drop in replacement for the old valve. The new Anderson Valve replaces the old housing and valve body perfectly.

Side by side comparison. Notice the properly labeled new valve on the right. Notice the better labeling on the face of the panel?

Oh, and very important to note here. This new part has been certified to be compliant with NSF/ANSI 61. This is the lead-free brass listing required for drinking water. And the best part? The Anderson water service panels are made in the U.S.A.!

The new all-brass assembly does not use the same plastic core with O-rings. It is an all brass body with teflon seals.

Preparing for Installation:

To replace the Anderson Kantleak water service panel in our fifth wheel, we had to remove all of the contents from our basement. Being we’re full-time RVers, this ended up actually being a good time to weed through any unwanted gear and parts in our basement cargo compartment.

After the space was clear, we removed a piece of the basement wall to allow us to access to the water-line attachment points and the back of the old valve. Since we had gained exposure, this was also a good time to inspect all the water lines and fittings.

We only needed two tools for the installation; a Robertson Head Screw driver and a pair pliers. We also had some extra shop towels and a lantern to provide better lighting.

Removing the old water service panel

Once we we were satisfied with our inspection, we shut off the water in our coach. We also opened the kitchen faucet to relieve the water pressure in the lines.  We made sure we relieved all of the pressure. The last thing we needed was water spraying all over our basement when disconnecting the lines.

Next, we placed some shop towels on the basement floor under the water lines to catch any residual water when we disconnected the lines from the valve fittings.

Installation Tip: Take a photo of the connection points so you have a reference of how the water lines should assemble.

Removing the old valve box is as easy as unscrewing and removing the eight screws that hold the valve box in the utility distribution center (UDC) wall.

Installing the new Kantleak water service panel

We replaced the old valve box with the new housing into the wall. However, we recommend not screwing it into place yet. Leaving it loose helps in getting the water lines reattached. By doing so, it allowed us to have a little more wiggle-room for tightening up the water lines and connections. We utilized the newly-designed swivel points for easy attachment of the water lines.

Once all the lines were reattached and tightened, it was time to fasten it into the new housing and the UDC wall by replacing the screws. After, we re-energized the water to the coach and inspected for leaks.

We made sure we cycled the valve through all of the positions while inspecting our work.

From start to finish, this installation took us only about an hour to replace the valve. It was a simple upgrade to our RV’s water system that will ensure leak-free camping for years to come.

An Important Note:

RV owners and installers need realize that Anderson Brass Company is not responsible for substandard piping or poorly installed fittings. These are a couple of issues you may encounter when doing the installation. We highly recommend that you prepare for those discrepancies by having necessary replacement parts and tools on hand.

  1. Great write up on a fantastic improved replacement product!

    For your readers, Anderson Brass will at the 2019 North American Heartland Owners Rally this coming June in Goshen, Indiana.

    1. Thanks for taking the time to read our blog post, Jim. Good to see you on here. See you guys soon! 🙂 -Dan & Lisa

  2. I have had numerous problems with the defective valve with the water bleeding back through the valve. I had a temporary fix and have ordered a new valve ( which is on backorder) if some thing like this happened in the auto industry ( which is regulated). They would have had a recall and paid for their engineering miscalculation. This need to come off of Anderson’s back and not those camping customers who trusted you. This needs to be a good faith repair by Anderson Brass Co.

    1. Fred, thank you for taking the time to read our blog. We appreciate your input. Our suggestion is to make contact with Anderson Brass Company and tell them of your repeal. Best wishes and safe travels! -Dan & Lisa

  3. Thanks for the review. Did they provide any guidance for the MANRV 102 RF? Would you post a video on that model?

  4. I have a defective valve on my 2018 Fleetwood Bounder. it needs replacing but somehow we in Canada can’t order them. Where and how do I get one. Even a repair kit would be helpful.. harry j

  5. I have the new kantleak RV water valve and I have a very difficult time rotating the tiny handle to fill it, and then rotate it back to normal use. There’s lots of resistance to rotate. The handle is too short to get any leverage to turn it. Is there a longer handle available to get more leverage? Does something need to be lubricated to enable the valve stem to rotate easier? It’s really a pain to use and I am searching for a solution? Thanks

    1. Jeffrey, I’m sorry for not seeing this sooner. If you’ve not gotten an answer to this issue, have you contacted Anderson Brass to see what needs to be done?

  6. Received my new brass valve only to find I can’t rotate the knob? What a disappointing event, especially after having to wait on backorder

    1. Rick, we are so sorry that you’ve had such a negative experience. Please contact Anderson Brass immediately to get it taken care of. -Dan & Lisa

  7. Hi Dan, I’m Dan also, retired Coast Guard, and live FT in a Heartland Big Horn in Arizona. Small world 🙂 I hope you can help me with something. BTW, Great post and just what I needed . . . mostly.
    I have recently purchased a water softener and filters. I will be routing the incoming city water from the valve to them and then back to the valve. Which seems pretty straight forward to me. I also want to dry camp and have the re-fill water go through the filters as well. Not wanting to have an external pump to do this, I was hoping to install an additional pump in the basement with a water proof power switch in the wet bay.
    Question: If I do this will the city water flow through the pump when off or would I need to put in a bypass of some kind?
    How do you fill your FW tank when you dry camp? (Assuming you do dry camp)

    1. Hey Dan! Welcome to our little corner of the world! Semper Paratus! We were in Arizona this past winter. We have a rule. Once the Rattlesnakes come out, we’re outta there! 😀 Enjoy your Big Horn!
