Your RV water heater pressure relief valve usually drips because heated water expands inside the tank. If the tank’s built-in air pocket becomes too small, pressure rises and the T&P valve releases a little water. However, constant dripping can also indicate excessive water pressure, mineral buildup, overheating, or a worn relief valve. Below, I’ll help

An RV tankless water heater usually shuts off at low flow because its flow sensor no longer detects enough water moving through the unit. Once flow drops below the heater’s minimum operating threshold, the burner shuts down. Low faucet flow, cold-water mixing, clogged filters, weak pump output, or mineral buildup can all cause this problem.

Your RV tankless water heater usually turns hot and cold because water flow through the heater keeps changing or falling below its required operating range. Excessive cold-water mixing, low campground flow, clogged filters, pump cycling, scale buildup, or an unstable propane supply can make the burner shut off and restart. I’ll help you narrow the

An RV water filter and an RV water softener do different jobs. A water filter reduces specific sediment, chlorine, tastes, odors, or contaminants based on its filter media. A water softener removes calcium and magnesium that cause hard-water scale inside your RV plumbing and appliances. If you are unsure which one belongs in your setup,

You regenerate a portable RV water softener by adding the correct amount of sodium chloride salt to recharge its resin beads. You then run water slowly through the softener so the brine can work, followed by a faster rinse that removes leftover salt and hardness minerals. Finally, test the outlet water before reconnecting the softener.

If your RV black tank valve opens but nothing drains, the most likely causes are a clogged tank outlet, hardened waste, a poop pyramid, or a gate valve that is not actually opening. A blocked vent, frozen waste, sewer hose problem, or inaccurate tank sensor can also create similar symptoms. The good news is that

Gray water usually backs up into an RV shower because the gray tank is full or wastewater cannot reach or leave the tank properly. Since the shower drain is often the lowest drain opening in an RV, rising wastewater commonly appears there first. If emptying the gray tank fixes the backup, tank capacity was likely

Your RV tank monitor usually reads full after dumping because waste, toilet paper, soap film, grease, or other conductive residue is still touching the tank sensors. The tank may actually be empty, but dirty sensor probes can continue sending a false FULL signal. Less commonly, the tank did not drain completely or the monitoring system

Your RV black tank valve should stay closed except when you are actively dumping or flushing the tank. Your gray tank valve is also best kept closed by default, although you can leave it open during some extended stays with full sewer hookups. Keeping both closed gives you better control over wastewater and helps prevent

Black tank treatment and tank rinsing do different jobs, so neither completely replaces the other. Tank rinsing physically removes loose waste and residue, while black tank treatment helps manage odors and waste between dumps. For the best black tank care, use both as part of the same routine.
