Question about Water Heaters

1 Answer

Rheem 22v50f1 Does this model have a back flow preventer? From time to time I'll get low hot water flow rate. It seems to solve itself when the city water pressure is increased for heavy morning consumption.

Water heater might have heat trap nipples that get clogged... but other issues have to be eliminated:

After city changed water meter the water is not consistently hot.


There are two things to check. First, check the inlet water filter on the heater. The changing of the meter may have introduced debris in the line and partially clogged the filter, causing flow issues that affect turn-on/turn-off of the unit. Also, the new meter may have changed the water pressure/flow rate into the house, If the filter is not the problem, have the inlet water pressure/flow rate checked. If it is too low, there may be some adjustment that can be made, or the city may have to replace the meter with a different unit.

Before calling service technician, open following link for Rheem troubleshooting resources.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

List of causes MIGHT include one of following:
Bad household circuit breaker that powers electronics, or loose wire inside outlet where tankless plugs in.
Tankless fuses and control board.
Water flow rate too low. Minimum .8 gallon required (depending on model)
Tankless inlet filter clogged.
Household aerators clogged at faucets.
Crossover at single-handled faucet
If installed, there can be crossover at mixing valve.
Faulty household check valve, including check valve on re-circulation system if that system is installed.
Restriction in household water line, such as clog at elbow.
Unequal pressure in household hot and cold lines, caused by restriction in hot line. When single-handled faucet turns on, the cold water pressure is higher so hot does not flow and tankless will not turn on.
Loose wire connection inside tankless.
Unit temperature set too high.
Unit temperature set too low.
Water temperature is very hot coming out of tap, so more cold is added, but that reduces amount of hot water flow, so tankless turns off because flow rate is too low.
On some tankless, if water is preheated by solar or other indirect source, the burner will not activate.
High mineral content in water > delime tankless yearly
Misaligned temperature sensor
Low gas pressure. Wrong type of gas. Undersized gas line.
Too many faucets on at same time.
Faulty tankless water valve. Water valve stuck.
Fluctuating household water pressure, for example MUD and PUD district water pressure problems or water well pressure.
Faulty household pressure reducing/regulating valve if installed.
Faulty household pressure tank, if installed -or- pressure tank needs to be installed.

I HAVE A 50 GALLON 5YR OLD RICHMOND HOT WATER TANK SOMETIMES YOU TURN ON HOT WATER AND IT RUNS FINE.THEN ALLOF A SUDDEN THE WATER STOPS AND PIPES BANG.WE HAVE 44PSI COMING IN FROM CITY


What you're describing is "water hammer". This problem, left unchecked, can cause big problems for your home's plumbing. Water hammer is result of quickly shutting off the flow of water in your home. The faster the rate of water flowing when it is rapidly shut off can result in very loud banging. The banging is caused by the pipes shaking in the walls, ceilings and any place they aren't secured. This repeated shaking causes soldered and glued joints to weaken and eventually fail. The most common sources for water hammer are toilets and wash machines, but even quickly shutting off a faucet can cause it too.

An short article about water hammer is here. Below is a link to images of products designed to arrest water hammer and associated noise.

My outlet(HOT tube is plugged. can i solve this?


Replace your tank. You are probably just days from the bottom of the tank falling out, which, my friend, is not a pretty sight.

Call the plumber if you are not able to use a soldering torch and pipe cutting tools.

Is the water heater in a basement or an area thats cold? A water heater jacket may help.

If not ,try setting the heat up a little higher on it until you have more then a 5 min hot shower.
