water heater

Hello, I have a portable water expansion tank, and it is leaking at the blue tip. I’m assuming it’s done for good due to corrosion. However, I don't know what to do other than to use the main water shut-off valve to stop it from leaking drastically. It has two valves connected on top of the...

A friend's water system has been working fine for at least 10 years. This week the T & P valve on the hot water heater started leaking. (Mounted on the top of the tank - don't have to drain tank to replace it.) My first suspicion was bad T & P release valve, so I replaced it. The new one did...

I had a white rodger water heater gas control valve go bad i ordered what i thought to be the same valve but when i recieved it i noticed it does not have the 2 wires that run to the thermal cutoff switch like the previous one! aside from the missing wires the valve is identical! Is there some...

My electric hot water heater stopped working over the weekend. It's a Bradford White RE350S6. It was installed new in 2017 as part of our new home build. I did some troubleshooting and determined the lower heating element was bad. I looked up the part number to be replaced 415-48642-00...

Is there an available low BTU tankless or hybrid tank/tankless unit suitable for retrofit applications in apartments, with existing 3/4" gas service? These apartments typically have a single bath with a single shower, and then a kitchen sink. Maybe a dishwasher (which could be plumbed to...

Hello, I installed a new Rheem 50 gallon natural gas water heater to replace my old Rheem 50 gallon. I noticed after it ran for probably a half-hour the plastic trim pieces around the water lines was melting. The vent is very simple just an elbow on about a 45 then straight out the block wall...

I installed a new Rheem water heater in my house. There was a problem with the gas valve leaking gas right away. My question is can I replace the valve with another just like it if the water column is the same? I have several other gas valves just not one with that exact number on it. They said...

My carbon monoxide detector went off recently, so I had the gas company out to test levels at our only gas appliances -- 38000 BTU Rheem* water heater and 80% efficient 88000 BTU furnace sharing flue venting. The gas company measured 45 ppm CO at the top of the unit when it was kicked on (and...

This 40 gal. electric Rheem water heater is only 4 years old. They called me because the tank was leaking. I've never seen one look like this. The lower element and thermostat almost look like they were on fire but the wires weren't burned at all. Can't tell if it's just from the water or if it...

Hi, DIYer here replacing galvanized piping throughout home with PEX. When connecting the PEX to the water heater lines (in and out) can I just use a threaded PEX fitting into the dielectric unions that are there from the galvanized to copper connection? There is already over 18 inches of copper...

I live in California (local temp ranges 40s in winter, to 80s in summer). I want to run a hot water line to an outdoor fixture, which will require about a 20ft outdoor run. There is no concern of freezing, nor waiting a little for the hot water, but I do care about energy efficiency. I wonder...

Hi everyone, I have a Bradford White heater that is just a few months short of being 12 years old. I'm going to change my furnace soon, and it requires disconnecting and moving the water heater to get enough room to change the furnace, and then the water heater will be put back where it was...

Based on your experience which water heater do you recommend? A.O. Smith or Rheem 40 gallon short water heater? I'm very confused on which one to choose. Beside these two water heaters do you recommend any other water heater?

Recently re-did the plumbing on my hot water heater because it was done with pex all the way to the nipple and that is a code violation. In doing this changeout I could not get the new compression type fittings to make a good seal with the plastic heat trap inside the pipes. They were causing a...

Plumbing/water heater- spots recently on ceiling downstairs, 2 story house. Condensation??? New water heater. Live in home now for 20 years but could happen anywhere. Got a new water heater in September on 2nd floor in a tiny closet. In that closet is a metal aluminum vent and also a white...

My father plans on installing a .67-.69 EF gas water heater, xg40t12dm40u0, to replace a 30+year old leaking gas water heater. Installation would be in the basement in a ranch house. He plans on venting through the chimney without a liner. I am in the trades as a carpenter around 7 years, I...

Hi. Hi have a 20 year old Bradford White. It is still running well except I detect gas smell intermittently (not every day) in the garage where the unit is and ALWAYS detect gas smell in the bathroom which is located directly above the garage where the water heater is. Every morning and...

Hello, I have a tankless water heater that has 1/2" MIP and my water lines are 3/4" FIP....so I need a 3/4" MIP to 1/2" FIP. I need this to be lead free/potable. Is there such a fitting? If not, how can I make this work? Thanks!

Hello Everyone, great forum. My water heater is leaking and needs to be replaced and I'm thinking about doing it myself with compression adaptors and flexible stainless steel corrugated connectors, and a gas flex line...

I just had my 40 gal water heater replaced. On its first heating cycle, the pressure release line squirted out 1-2 cups of water. I opened the manual, and on page 6 was a giant warning about thermal expansion tanks being required in the presence of a backflow preventer (which my building does...
