the water pressure is fluxuating and the pressure tank is making a thuding noise..the pressure on the tank goes from 20psi to 40psi. what could be the problem?

When does it fluctuate? When the pump is on, or off?
Some pressure tanks need to have compressed air blown into them periodically, does yours?

i'm with Richie with this one, i've got not got self assurance it is your water heater in any respect. on condition that frequently the water heater is likely one in each and every of the 1st issues hooked to the water grant, in case you have an exterior or underground leak, the working water could pass the sound during the pipes to sound like it incredibly is the heater. FYI, a 40 or 50 gallon water heater will final incredibly a protracted time without power, it provides and mixes new water with the already warm water so it incredibly is going to take even longer to word without a good thermometer. i'm assuming you meant one in each and every of two "heater coils" no longer thermostats. If a plumber did it, he/she could of flushed the tank at that factor. in some situations sediment on the backside of the tank will overheat, burn out the element and make a boiling sound, yet could of stopped quickly after turning it off. city water, seem on the meter, properly water turn off the pump, (some city water residences have an auxiliary pump), so examine that to boot.

The pump is cavitating (air in the eye/suction of the pump. Make sure the suction line/eye of the pump is not sucking in air through a leak or bad gasket. Then, to stop cavitation, try this: If there is a bleeder valve on the discharge of the pump, crack it open with the pump running and let the air be released from the eye of the pump. If there is noot bleeder, close the discharge valve, start the pump, and slightly open the discharge till pump smoothes out, then VERY slowly open the valve fully.

sounds to me like the tank needs to be pressurized.......on the top of the tank there should be a filler valve that will look like the end of a valve stem of a tire on your car......you can pressurize the tank with a hand or foot pump pressurize the tank to 35#'s air pressure........the thud you are hearing is the spring flap in the tank shutting prematurely. you will also find you will have better water pressure from your sink and shower faucets

SOUNDS LIKE THE TANK IS BOTTOMING OUT. GO UNDERTHE HOUSE AND WETCH THE GUAGE. HAVE SOMEONE TURN THE WATER ON DOES THE NEEDLE HIT ZERO??? IF SO YOU NEED TO PUT SOME AIR IN YOUR TANK. YOU HAVE A 20-40 SWICTH SO PUT 28 PSI INTO THE TANK. ALSO WHILE YOU ARE UNDER THERE MAKE SURE TANKS NOT WATER LOGGED. THERE SHOULD ONLY BE 2-4 GALLONS OF WATER IN IT. ALL YOU HAVE TO DO IS PUSH ON THE TANK IF IT FEELS LIKE IT IS FULL, YOU NEED A NEW TANK.
