freshwater

My wife and I just bought a new 2026 Cougar MLWE, love it so far. This is the first RV we have owned that has two freshwater fill ports into essentially the same tank. The city water intake is on the other side of the trailer within the "water closet", these are both filling the onboard...

What kind of overflow does the tank have? Would like to see clear photo or line drawing. Google showed me some other-make diagrams that were pretty good but the Winnebago diagrams aren't clear to me. Asking because it raises my curiosity -- on our January trip I didn't get to shut off the water...

I have a KIB Panel on my 2018 Ventana to display tank levels. The freshwater indicator is erratic. It moves up and down jumping between 20 to 100 percent. The indicators for the other tanks and battery work fine. Sometimes it will settle at full when topping it off. The coach has the...

Provided some tests work out, I'm going to install a waterproof ultrasonic sensor in the top of my freshwater tank. Why? Because I'm a geek for this stuff... but more about proving to myself there's far better (and way more accurate/reliable) tank level measurement methods. This will require...

I am unable to fill my freshwater tank, (which is 42 gallons) past 15 gallons. I have tried slowing down to a trickle and it backs out the vent tube. Also I am getting water on the kitchen floor coming from under kitchen cabinet (which is where the fill tube runs) when it gets up to the part...

Hey all - 2023 Georgetown GT7 36D7 How do I fill the freshwater tank from bottled water without a pressurized source? We are boon docking for a few days and have someone coming to collect the black/grey tanks, but need to know how we can refill the freshwater tank. I read about using the...

Does anyone know if the factory installs freshwater tank heaters or are they just on the black and grey tanks? Thanks for any help

Went to winterize our 2022 FW 31W last week and discovered a previously unrecognized assembly problem that is likely common across this model plus other similar Thor models with an under-bed freshwater tank. When I opened the 1" PVC tank drain valve to the outside, water began to pool and run...

I just purchased this used toy hauler and all of the literature, both paper and digital, specify a 174 gallon freshwater tank, but when I filled it to sanitize and flush it, it only took 75 gallons. After draining it I refilled with fresh water and this time was able to fill 80 gallons before it...

Looking to winterize my 2518 for the 1st time. The two options seem to be using a hand pump that connects to the city water inlet or a permanently mounted pump converter installed before the pump. The hand pump at the city water inlet seems the easiest but then isn't the trailer water pump...

I need to remove and replace my freshwater tank on our 2016 Bighorn 3760EL. Any tips, tricks and suggestions are appreciated Also thoughts on underbelly removal, I will most likely have to cut it by the tank from side to side then drop the underbelly. Hoping only needing to do one cut. Thanks

Hello, I am new to the forums and a new owner of a 31’ 1976 Sovereign International twin center bath. Winter is coming and we need to drain the freshwater tank. I have researched this and it seems the tank in this model year does not have a drain valve on the bottom and the only way to drain it...

Help! I’m a newbie. But I’m sure this is not normal. I arrived to find a waterfall running from the entire underbelly of the trailer. I turned off the water supply and waited. When it finally stopped I filled the fresh water tank only to have the same thing happen. The underneath of the trailer...

Hello everyone from St George Utah! I purchased a 2004 keystone cougar sport 2100 RK with an enclosed underbelly. So far so good except that the drain to the freshwater tank is up in the underbelly and I cannot access it. This is not the first RV I have owned, more like the 7th and I have always...

Does anyone know where this would be? I can’t even find my fresh water tank!! Please help!

It's an often been discussed topic but I don't see anything here on the Seismic. Has anyone traveled with a full freshwater tank? Specs say the Seismic 4113 has a 100 gallon freshwater capacity. Many years ago, our Cyclone 370C hauled 100 gallons with no issues. Our Work & Play hauled 110...

Hi all, I have a 2014 Microlite. I was wondering if anyone has replaced the drain valve on the potable fresh water holding tank? It is only made of some kind of rubber and is very hard to turn by hand (I have to use pliers). I'm afraid it's going to break off after to many openings and...

Lately, I've noticed the concrete where our trailer is parked is damp below the freshwater tank dump valve. I've looked at it and it's damp at the valve. No drips, just a damp circle on the concrete. Is there anything I can safely use to lubricate the gasket...plumber's grease (made from real...

I have a 2019 Rockwood Mini Lite 2509s, and I've seen and read many things on the internet about replacing these valves. But I've not seen a similar post or video about the specific way mine is mounted on my Mini Lite. Am I right assuming that I cannot easily unscrew these white screws? I think...

Just bought a new 2025 stealth f2800. They filled the fresh water tanks at the dealership no problems. Pulled it home 350 miles parked in the driveway and both fresh dump valves are leaking above the valve. Went to see if maybe it was loose and the back valve came off in my hand no pvc glue to...

I just bought mt RV, took it camping right from the dealer, and it was great! However, before we left the camp ground i topped off my fresh water tank in case we got delayed and needed water. Not 10 miles from the camp ground, rounding curve on the freeway with some ruts in the lane at highway...

I recently had an issue where we filled our fresh water tank, drove to a boondock site and later realized the tank showed 70% on the display. We were thinking/hoping the gauge was wrong so we opened up the closet floor to get a glimpse of the tank. Sure enough, it was about 2/3 full. I found...

I fill my fresh water tank when the rv is level. When it starts to drip out of the overflow line I close the overflow valve and stop filling. When I arrive at my destination and level up, I then open the over flow valve so I can run the water pump. When I open it I lose alot of water...

Hello, I have a new to me 2018 Georgetown XL 378TS and was thinking about sanitizing the fresh water tank. I’m concerned about the ice maker/water dispenser in the residential fridge, the washing machine, and also the water heater. So, I was thinking that bypassing them would be best. Any...

Hi folks I am assembling materials for plumbing, and considering using an old used water holding tank I found in the planet fitness parking lot.. Yeah yeah laugh all you want, but I am on a budget and it seems like a good tank- 70 gallon white plastic tank, fits nicely under the bed, just...
