troubleshooting and repair guide.The Sealand Traveler RV toilet valve is a very important mechanical device that is in charge of the flow of fresh water in your RV toilet bowl. This is a water tap that usually has a foot pedal or hand lever to make sure that a bowl is flushed when a toilet is flushed, and partially full so that it has a sanitary liquid seal. Complete Sealand traveler RV toilet valve troubleshooting and repair guide. Discover how to diagnose leaks, replace faulty valves, fix water flow issues, and maintain your RV toilet easily. This is the part usually sought by RV owners when they have faced some typical plumbing disappointments like water leaks, a toilet that does not stop running, or a pedal that does not add water.

Although not directly affecting the comfort, the structural integrity of your mobile home is imperative in the preservation of a functional valve. A defective valve may cause the floor to be wet in the bathroom or worst still, an overflowing tank of black water. This handbook will offer an in-depth examination on the procedures of locating valve problems, precautionary measures when performing repairs and a step-by-step procedure to replace your RV plumbing system.

Sealand Traveler RV Toilet Valve is fitted to the toilet.

The Sealand Traveler RV toilet valve (which is frequently produced as Dometic) is an assembly, typically white or black plastic, that is found just below the bottom of the toilet, typically in the back of a plastic shroud or pedal cover. It serves as a filtration system of your freshwater. Depressing the flush pedal causes a cam or lever to act against a plunger which is spring-loaded inside the valve, and by which force a pressurized stream of water is forced into the rim and bowl wash.

This valve fits particularly the low pressure, gravity-flush systems prevalent in travel trailers, fifth wheels and motorhomes. The Traveler system utilizes the constant pressure of your RV water pump or cheap city water connection in lieu of a tank of water, as is the case with a residential toilet. It is a high-frequency moving component and hence it is usually among the first parts to wear after a few seasons of use.

There are several issues that are common with the Toilet Valve.

The Sealand Traveler valve may have several problems, the majority of which are brought about by mineral build up, freezing in winter or mechanical wear and tear in general.

Water Leaking: this is one of the most frequent complaints where the floor is dripped with water through the valve body. This mostly shows a broken plastic case or a broken internal O-ring.
Valve Failing to Close: In case the spring in the inside of the valve becomes weak or there is some debris trapped in the seal, the valve might not fully close. This effectively leads to a running toilet, which wastes water all the time and fills the holding tank.
Weak Flush: In case internal filter screen would get clogged with sediment or calcium deposits, the flow of water into the bowl would be limited which causes a poor rinse.
Continuous Water Flow: In case the flush pedal fails to snap back, the plunger of the valve is open. This is usually an indication of a defective spring cartridge placed near the valve of the water.

Indications Your Valve requires replacement.

Although some leaks can be solved by tightening a connection, there are still symptoms that well spell out that the valve assembly has failed and thus requires replacement.

Observable Cracks: Plastic valves are very vulnerable to damages when they are left with water when the water is allowed to freeze. Any minute crack will cause water to spray under pressure.
Water Pooling: When you see the water around the bottom of the toilet that is not dripping out of the floor flange, then it is probably dripping off the back of the unit at the valve.
Less Water Pressure: When your sink has tremendous force and the toilet streams, then the inside bypass of the valve is probably blocked.
Unusual Noises: During the flush cycle, there may be unusual high-pitched whistling or humming and this may be an indication that the inner diaphragm or seals are vibrating because of failure.

Before repair it is important to consider the safety factor.

We are concerned with your safety at safetravelquest.com. Plumbing in RVs implies high-pressure water, as well as possible work in unsanitary conditions.

Switch Off Water Supply: Before putting your hands on the valve make sure you switch off your RV water pump and shut off the city water hose.
Drain the System: Despite the absence of water, there are still water lines pressurized. Keep holding the flush pedal until all the water ceases to flow so that the lines are emptied.
Wear Gloves: The valve is in an area of high contamination, although it contains fresh water. Use nitrile gloves to cover yourself against bacteria.
Be ready on Spills: have a small bucket or a few towels ready. When you detach the water line with the water valve, some little water would definitely spill away.

How to change a Sealand Traveler RV Toilet Valve.

A replacement of the valve is a relatively simple DIY task that can be completed in less than 30 minutes and with minimum equipment.

Tools Needed:

Phillips-head screwdriver
Adjustable wrench or pliers
Small bucket or towels

Step-by-Step Guide:

Take off Covers: To gain access to the valve and spring cartridge, remove the plastic pedestal cover or pedal shroud.
Disconnect Water Line: Screw the freshwater supply line out of the bottom of the valve with your wrench. Use your bucket to pick up any drips.
Unscrew Valve: Find the two screws with the Phillips screwdriver to ensure that the valve is attached to the toilet base. Take them carefully not to drop behind the toilet.
Take the Old Valve away: Push the valve down the bottom. It might require wiggly to loosen it on the cam lever.
Install the New Valve: Position the new valve with the plunger mushroom cap fitting in the proper position against the cam strap of the pedal. Install the two mounting screws once again.
Reconnect and Test: screw the water line once again at the valve (hand-tighten, followed by a quarter-turn with a wrench). Switch on the water and rinse a few times paying attention to whether the connections are moist or dry.

Tips to enhance the value life of the valve by maintenance.

It is not hard to maintain a few simple maintenance habits in order to avoid frequent replacements.

Frequent Cleaning: Sometimes spray the area of the valve with a light cleaner to avoid dust and grime intruding on the movement of the pedal.
No Hard Chemicals: Do not add bleach or other strong solvents in the inside of the toilet bowl, this can ruin the rubber seal in the vacuum breaker and ball valve, which will cause the performance of the water valve to be indirectly affected.
Apply Plumber Grease: A little silicone-based plumber grease on the moving components of the pedal can stop the friction which wears out the actuator of the valve.
Seasonal RV Preparation: Winterization is the most important single process of maintenance. Position non-toxic RV antifreeze to make sure that no water is left inside the valve to freeze and crack the plastic housing.

Sealand Traveler Valve vs. Other RV Toilet Valves

There are not equal RV toilet valves. The Sealand Traveler valve fits only Sealand (currently, Dometic) 500, 700, 800, 1000, and 2000 series toilets.

Fitment: Although most aftermarket valves resemble each other, it is always a good idea to check the model number of your toilet (it is normally printed on a label on the back of the base). Improper seating and instant leakage may be a result of using the wrong valve.
OEM vs. Aftermarket: Dometic has been very successful in providing Original Equipment Manufacture (OEM) parts which fit better, and the seals are of higher quality, although many travelers have managed to use reputable aftermarket “kits” which include enhanced stainless steel mesh filters to prevent clogs.

Cost Considerations

The price of repairing a Sealand Traveler toilet valve is lower than other repairs of an RV.

Item	Estimated Cost
Part Cost	$25 and 45 dollars or so
Professional Repair	$120 to 180 dollars

Savings in Total: Replacing your RV by yourself will save you a lot of money, as well as keep you offline, when your vehicle is in a repair shop.

Frequently Asked Questions

Is there a leak in my Sealand Traveler toilet? Why?

The leaks are usually a result of a broken valve body or a broken O-ring in the valve. In other instances, the actual leak can be the one that is coming off the higher up the back of the toilet in the form of the so-called vacuum breaker and the dripping water falling on the valve.

Does the valve require many efforts to replace?

No, it is among the simpler RV repairing. The majority of the owners discover they can get the job done by using a screwdriver and approximately 20 minutes of time. The valve does not normally require the removal of the complete toilet to reach.

Would it be possible to fix the valve rather than to replace it?

Although it is possible to open up the valve and change the internal O-rings, the rest of RVers would find it much easier to change the whole assembly. Failure usually happens in the plastic housing, this cannot be easily fixed.

What is the lifespan of an RV toilet valve?

An unbroken valve will last between 5 and 10 years. Nevertheless, the valve can be ruined in just one night after a single case of inappropriate winterization (when one lets the water freeze inside).

Final Practical Advice

The Sealand Traveler RV toilet valve is a small component which contributes a huge role in your comfort when traveling. When you find that there is a small drip or that a pedal is not moving like it needs to, then you should deal with it as soon as you notice otherwise your subflooring of your RV may get a bit of water on it. In your RV emergency kit, always have a spare valve as they are cheap and can save a vacation in case the main valve fails on you when you are in a distant campground. Always have your model-specific manual on hand as the owner of your particular Dometic/Sealand, available with diagrams, and part numbers, as instructed.
