Anderson Kantleak RV Water Service Panel Replacement

We upgraded our Anderson Kantleak water service panel with a much improved and better engineered retrofit water service panel. Our old Anderson Kantleak had plastic fittings that leaked; making the valve system unreliable. However, as you’ll read further, you’ll notice the vast improvement of the the new Anderson Kantleak’s fittings. Plus, we’ll include how we installed it.

Disclosure: We received compensation from Anderson Brass to install and field test this product. After which, we send back our evaluation to the company. We then wanted to share our findings report on the product as well as installation procedure as it’s applicable to our audience of readers.

How the Anderson Kantleak RV Water Service Panel Valve System Operates

Anderson Brass’ Kantleak water service panel has a knob in the UDC that rotates either left or right to select how water will be provided to our coach. The water service panel has four function fill valve supply settings:

    • CITY FIXTURES – Supply water to the fixtures directly from campground or RV park water hook up.
    • DRY CAMPING – Supply water to the fixtures directly from the on-board water tank.
    • TANK FILL – Supply water to the holding tank from the city water hook up.
    • SANITIZE / WINTERIZE – Supply sanitizing / winterizing fluid to the fixtures from inlet connection (via water pump).

Anderson Brass Old Model #200RV Kantleak RV Water Service Panel

The original Anderson Kantleak Water Service Panel model #200RV had a plastic main body with a rotating knob. The valve inside would click and lock into each position as we would rotate the knob to the setting we needed (described above).

The original water service panel valve had an internal plastic core that relies on several rubber O-rings to maintain pressure and keep the valve functioning properly. It also had four positions for selection (described above).

However, the old model was hard to read what position the knob was actually. In fact, we had to get our own label maker out and label the settings to make it more clear for our own use.

Unfortunately, the former Kantleak valve was prone to failure; especially if the knob was rotated while under pressure.

In the past, many RV owners would call Anderson Brass Company seeking guidance and complaint of their leaky valves. Anderson Brass would provide replacement cores if the valve failed.

However, after so many complaints, Anderson Brass went back to the drawing board to see how they can improve the valve system to alleviate leaking. But, did they come up with a solution?

The NEW Model of the Kantleak RV Water Service Panel

Anderson Brass Company redesigned and developed a much-improved Kantleak water service panel. I can now report that the new Kantleak retrofit panel that fits our fifth wheel is working as Anderson Brass promised. The new Kantleak alleviates those valve issues or failures. It will revolutionize the RV industry for water selection valves.

The new Kantleak’s construction and assembly is top notch. It’s constructed with all brass fittings 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. In other words, no more plastic fittings that can fail.

Anderson Brass’ product developers have designed the new Kantleak water service panel knob with three position settings instead of the former’s four positions. The knob’s positions are now marked with easy-to-read lettering. No need for us to get our label maker out.

Also, the new Kantleak valve knob rotates smoothly unlike the old one. And here’s the bonus! It’s a direct drop in replacement for the old valve. The new Anderson Kantleak replaces the old housing and valve body perfectly. So, there’s no altering or modifying to upgrade to this water service panel.

Oh, and very important to note here. The new model Kantleak brass components have 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. The new Kantleak has an all brass body with teflon seals.

Anderson Kantleak – Brass Valve Replacement

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 that 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 where our water service components and hoses are located.

After clearing out our fifth wheel’s basement, we removed a section of the basement wall to allow access to the water-line attachment points and the back of the old valve. Oh, and since we had gained exposure, this was a good time to inspect all the pex lines, pex fittings, clamps and our water pump.

We only needed two tools for the installation; a Robertson head screwdriver and a pair of 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. The last thing we needed was water spraying all over our basement when disconnecting the lines.

Next, we placed a couple towels on the basement floor under the water lines to catch any residual water upon disconnecting the water pex lines from the valve fittings.

Before we proceeded with disassembling the old panel, we took a photo of the connection points so we had a good reference of how the water lines should look like when assembled correctly.

Removing the old Kantleak water service panel was easy. We simply unscrewed and removed the eight screws that held the old water service panel in the utility distribution center (UDC) wall. Then we disconnected all fittings from the old water service panel and pulled it out.

Installing the new Kantleak water service panel

We replaced the old water service panel with the new Kantleak into the wall. However, we recommend not screwing it into place yet.

Leaving it loose gives the water lines a little play in getting them reattached. 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 water 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 our Kantleak replacement installation took us 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.

  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!
