RV Black Tank Maintenance and Repair: Professional Guide
The black tank system is essential to RV sanitation. Proper maintenance prevents costly failures and health hazards.
Tank Basics
Most RVs have black tanks ranging from twenty to forty gallons capacity. The tank collects waste from the toilet. A level sensor indicates fullness. Never let the tank exceed three-quarters capacity before dumping—overfull tanks cause backups and sensor failure.
Chemical Treatment
Use RV-specific tank chemicals, not household products. These break down waste and control odor. Add chemicals after each dump and before extended trips. Follow product ratios carefully—typically one quarter cup per twenty-gallon tank. Use enzyme-based treatments for better breakdown. Avoid formaldehyde-based chemicals as they’re harmful and increasingly restricted.
Maintenance Protocol
Dump the tank only when full. Partial dumps allow solids to accumulate and dry out, causing clogs. After dumping, add water and chemicals, then run the toilet to distribute treatment through the tank. Never pour grease, feminine hygiene products, or non-RV toilet paper down the system—these cause blockages. Use only RV-specific toilet paper that dissolves quickly.
Common Problems and Solutions
Foul odors indicate inadequate chemical treatment or a dry trap. Add chemicals and run water. Slow drains suggest partial clogs from improper waste disposal. Try adding hot water and enzyme treatment first. If that fails, use a tank cleaning wand or professional service. Backup into the bathroom means the tank is full or severely clogged—dump immediately and assess the problem.
Prevention
Keep a maintenance log of dump dates and tank fullness. Inspect hoses and connections seasonally for cracks or leaks. Replace the toilet flapper every two years. Run the black tank flush system after each dump if your RV has one. During storage, leave the tank valve open to prevent bacterial growth and odor.
Professional Service
If clogs persist after chemical treatment and hot water, hire a professional tank cleaning service. They use specialized equipment to clear blockages without damage.​​​​​​​​​​​​​​​​

Finding and Stopping RV Leaks
My Professional Guide
Water intrusion is the leading cause of RV structural failure. Early detection prevents costly damage.
Detection Method
Perform a systematic water test on a dry day with all interior water systems off. Starting from the roof, spray water using a garden hose while an observer monitors interior surfaces for leaks. Progress systematically: roof penetrations first, then windows, windshield, doors, and exterior seams.
Primary Leak Points
Roof vents, air conditioning units, antennas, and satellite dishes are high-risk areas. Windows and windshield seals fail regularly due to thermal cycling and UV exposure. Door seals, storage compartment seals, and wall-to-roof seams are common failure points. Check the undercarriage for gaps and compromised caulking.
Permanent Sealing Solution
Remove all deteriorated caulk completely using a putty knife. Clean surfaces with degreaser to ensure adhesion. Apply marine-grade flexible sealant rated for RV use, not standard caulk. For large seams and roof penetrations, layer Eternabond tape over fresh sealant for maximum protection. Allow full cure time per manufacturer specifications before water testing again.
Maintenance Schedule
Inspect seals biannually, especially before winter. Touch up compromised sealant immediately. Replace window and door gaskets every five to seven years.​​​​​​​​​​​​​​​​

Replacing Rotted Slide-Out Flooring: A Complete Guide
Start by assessing the damage. You need to know how much of the floor is actually compromised. Check for soft spots by pressing on the material with a screwdriver—if it punctures easily, that area’s gotta go. Mark out your work sections. For safety, you’re not gonna pull the entire slide out at once if there’s significant rot. Instead, extend it partially, maybe two to four feet, and build temporary support braces under the corners and middle to distribute the weight evenly.
Next, disconnect anything routed through the floor—plumbing, electrical, any cables. Take photos before you start so you know where everything goes back. Once it’s clear, start removing the old flooring material. If it’s OSB like yours, it’ll come out in chunks. Cut it out carefully with a reciprocating saw or circular saw, working in manageable sections. Wear a respirator because you don’t want to inhale all that dust and mold spores.
Now here’s the critical part—inspect the frame underneath. Check all the structural supports, the I beams, anything metal. If there’s rust or corrosion, you need to address that with a wire brush and rust converter before you put new material down.
Once the frame is clean and sound, measure carefully and cut your replacement plywood. Use exterior grade plywood, not OSB—it’ll last way longer. Apply a heavy duty exterior primer to all sides and edges before installation. Let it cure fully. Then install it, making sure it sits flush and level on the supports.attach directly to the lower wall framing.
After the plywood is down and secure, apply your sealant. Use a quality exterior sealant around all edges and any penetrations. Then glue your aluminum undercoating directly to the bottom using a marine grade adhesive. Work in sections if you’re doing this from underneath—four foot sections are manageable, eight foot gets tough. Make sure you get good contact and let the adhesive cure per the manufacturer’s specs.
Finally, seal all the joints between your aluminum sections with appropriate sealants—Eternabond tape or equivalent works great. That keeps moisture out completely.

If your battery’s dead and the charger light’s not on—or it’s blinking red—90% chance your converter’s toast. Here’s why it happens and how to fix it without a shop:

Why it dies:

• Converter turns shore power (120V) into 12V to charge batteries.

• Over time: heat kills it, bad wiring fries it, or you leave it plugged in forever and it overheats.

• Signs: Lights dim, fridge won’t run on shore, battery stays at 11.8V even after hours plugged in.

Quick test:

Plug into shore → check battery voltage. Should climb to 13.5–14.2V. If it sits at 12.6 or lower—converter’s likely bad.

Replace it (30–60 mins, $150–$300):

1. Kill power: Unplug shore, flip breaker, disconnect battery cables (neg first).

2. Find it: Usually behind a panel near battery—look for big box with fans, labeled “Progressive Dynamics” or “WFCO.”

3. Unbolt: 4–6 screws, pull it out. Note wire colors—black/red/ground.

4. Swap: Match new one (same amps—30A or 55A usually). Plug wires back (tight!), screw in.

5. Test: Reconnect battery, plug shore—voltage should jump. Run lights/fridge—good? Done.

Pro tip: Get a Progressive Dynamics PD4655V—quiet, reliable, has built-in battery protect. Avoid cheap Amazon junk.

If voltage still sucks after swap: check fuses, corroded terminals, or bad battery.

How to Find and Fix a Leak on Your RV Rubber Roof
Finding a leak in your RV is stressful, but most of the time it’s an easy fix if you catch it early.
Step 1: Find where the leak is actually coming from
Water is sneaky — it can run along rafters and drip far away from the actual hole. Go up on the roof and look around all your roof penetrations: the air conditioner, vents, TV antenna, plumbing vents, and anywhere there’s sealant. Look for cracked, dried out, or missing Dicor sealant.
Step 2: Clean the area really well
Use your regular roof cleaner or isopropyl alcohol so the new sealant will actually stick.
Step 3: Fix it
For most small leaks, just lay down a nice thick bead of Dicor Self-Leveling Lap Sealant right over the old stuff. Smooth it out with a gloved finger or plastic putty knife.
If you’ve got a bigger crack or seam issue, clean the area, lay down EternaBond RoofSeal tape over it, and then put Dicor over the edges of the tape. That combo is basically bulletproof.
Quick tip: After you fix it, run a hose over the roof for a few minutes and have someone inside watching for drips. That way you know you actually got it.
Catch these early and a $15 tube of Dicor will save you thousands in water damage. Let it go too long and you’re looking at a full roof replacement.
Safe travels to everyone! Dm if you’re in need of help with anything! Ty, ij

How to Maintain and Care for Your RV Rubber Roof
These membrane roofs (EPDM or TPO) are actually pretty tough, but they take a beating from the sun. If you ignore them, they’ll dry out, crack, and start leaking — and that’s an expensive fix.
What you’ll need:
Best RV Rubber Roof Cleaner (like Dicor RPCRP or Camco Pro-Tec)

Soft bristle brush or roof broom

Rubber roof protectant (303 Aerospace Protectant is the gold standard, or Dicor’s Rubber Roof Protectant)

Lap sealant (Dicor Self-Leveling Lap Sealant) for any seams that look sketchy

A sturdy ladder

How to care for it:
Clean it — Park in the shade if you can. Mix the cleaner, scrub gently with your soft brush, and rinse really well. Don’t use household cleaners — they can damage the rubber.

Let it dry completely, then spray on 303 Protectant. Let it soak in for a few minutes, then wipe off any excess with a clean cloth. This stuff keeps the rubber flexible and protects it from UV damage.

Inspect the seams — Pay special attention to anywhere there’s a vent, skylight, antenna, or edge. If the sealant looks cracked or pulling away, clean it and lay down a fresh bead of Dicor Self-Leveling Lap Sealant.

Do this cleaning and protectant routine every 3 to 4 months, and you’ll easily DOUBLE the life of your roof. It’s boring maintenance, but it beats having water dripping on your bed during a rainstorm ! - certified tech please message me if you have any questions ! Thanks for reading!

Travel Trailer Tire & Axle Maintenance Guide: Stay Safe, Avoid Blowouts & Costly Breakdowns

Travel trailer owners — this is the stuff that keeps you from getting stranded on the side of the highway with a shredded tire or seized axle. Do this every trip (quick check) and every 3–6 months (deep dive). Takes 15–30 minutes. Saves thousands.

Why It Matters

•	Travel trailers are heavy and sit parked for months. Tires dry-rot and axles lose grease.

•	70% of RV roadside breakdowns are tire/axle related.

•	Proper maintenance = better MPG, no sway, and no $800+ roadside tire change.

Tools You Need (Cheap & Essential)

•	Tire pressure gauge (digital)

•	Tread depth gauge

•	Torque wrench (or at least a star pattern)

•	Jack stands + trailer jack

•	Grease gun (for axles)

•	Flashlight & mirror

Tire Maintenance (Do This Every Time You Tow)

1	Cold Pressure Check

Before every trip (tires cold). Find your trailer’s placard (usually on the tongue or door jamb).

Typical: 50–80 PSI depending on size. Never guess — underinflation = heat buildup = blowout.

2	Visual Inspection

◦	Cracks in sidewalls (dry rot)

◦	Bulges, cuts, or nails

◦	Uneven wear (means alignment or overload issue)

◦	Tread depth: replace at 2/32” (use a penny — Lincoln’s head showing = done)

3	Rotation & Balance

Every 5,000–8,000 miles or once a year. Trailer tires wear faster on the outside.

4	Spare Tire

Check pressure & condition every spring. Most people forget theirs until it’s flat too.

Pro Tip: Buy TPMS sensors (Bluetooth ones are ~$40 for 4). They save lives.

Axle Maintenance (The Part Everyone Ignores Until It Fails)

1	Bearing Repack (Every 12 months or 12,000 miles)

◦	Jack up one side at a time (use stands).

◦	Remove wheel/hub.

◦	Clean old grease, repack bearings with marine-grade wheel bearing grease.

◦	Replace seal if it looks cracked.

◦	Torque hub nut to spec (usually 15–20 ft-lbs + cotter pin).

2	Inspect Axles

◦	Look for bent axles (common after potholes).

◦	Check shackle bolts & hangers for rust/cracks.

◦	Grease any zerk fittings on suspension.

3	Never Overload

Use a scale (CAT or truck stop). Stay under GVWR and GAWR. Tongue weight 10–15% of trailer weight.

Safety Rules That Can Save Your Life

•	Never jack up on the stabilizer jacks — they’re NOT for lifting. Use the trailer jack or frame points only.

•	Torque lug nuts: 80–120 ft-lbs (check your manual). Do it in star pattern, re-check after 50 miles.

•	If you feel sway or hear grinding — pull over immediately. Could be a bad bearing.

•	Replace tires at 5–7 years old even if tread looks good (rubber hardens).

•	Carry a spare tire, jack, and roadside flares.

When to Call a Pro

•	Bent axle

•	Hub leaking grease

•	You hear clicking or grinding while driving

•	Any doubt — better $150 shop visit than $2,000 tow.

Do this checklist once and it becomes habit. Your trailer will last longer, tow safer, and you’ll sleep better knowing you’re not one pothole away from disaster.

Dumping tanks is intimidating at first—nobody wants a poop fountain. Here’s the real way to do it clean:

1. Gear up: Gloves, hose (at least 10 ft, sewer-rated), sewer donut/flange (cheap at Walmart), and a trash bag for gloves.

2. Park smart: Back up so hose reaches dump station—keep it downhill if possible.

3. Connect: Push hose into station hole, twist donut on tight—no leaks.

4. Order matters: Open BLACK tank valve FIRST—let it drain fully (gross, but it rinses the line). Close.

5. Flush with gray: Open GRAY next—its cleaner water pushes everything out. Let it run till clear.

6. Rinse: If station has a hose, spray the connection. Close valves, disconnect slow—let gravity finish.

7. Clean up: Wipe fittings, bag gloves, hose down everything.

Pro tips:

• Never open black with gray—backflow stinks.

• If it splashes, you’re too close—use longer hose.

• Practice on a quiet dump station first.

Takes 5 minutes once you’re used to it. No drama.
