    Water hammer at hot water heater

    I’m hearing what sounds like a water hammer in the pipes near my hot water heater(tank). With no water running, it knocks about every few seconds to a few minutes. I turned off the water heater at the breaker, electric only. Waited a day and used up what hot water was left. The knocking...

All the information they gave me is this: 'Provide a few sizing...

    Cold Water not going into Tank

    I recently replaced my water heater and also the hoses that connect to the pipes in the wall. I did have to reem on the wall pipes pretty good, but do not feel I broke or bent then in any way. However, with everything connected and ready to go, I turn on the cold water valve, and it flows for...

    Dielectric Union Needed?

    I just had a Rheem Power Vent unit installed. The technician installed the copper pipe from the house directly to the two heat trap nipples. The nipples are silver in color so I assume made of steel. I contacted Rheem to confirm if those nipples acted as dielectric unions and their response...

    New Pressure Relief Valve Leaks

    My water heater TPR valve was leaking - not much - couple ounces/day. I replaced it. It's still leaking. Not quite as much, but it still dumps a couple ounces/day. Even if both temperature settings are set low (both the same, 120 degrees). Does this mean the water heater is bad? It's a...

    Circuit for heat exchanger water heaters

    Hi, I'm a bit stuck on a hot water circuit that I'm trying to come up with for a small guest house. I have 6 water heaters with built-in heat exchangers that I'm planning to connect to a loop, itself fed by a solar water heater and/or a heat pump. I came up with 3 options (see drawings), but...

    Water heater leak from top. Am I on the right track?

    I have a probably 13 yr old water heater, so I know its getting up there. I just got a leak on what looks to be the hot water outlet. (The leak is hot). It doesnt look to be the joint, and it seems to be coming from under the cover/red cap. I found some threads talking about dielectric...

I installed it and it works but after about 3 months i started to hear a loud banging noise when the water was in use. I researched it and most people said it was jackhammering, i think that...

    Tankless Water Heater Replacement

    Hello, our Eemax EX280T2T water heater recently sprang a leak. We're hoping to replace it but the reviews for the same unit are not that great and we'd like a solid, reliable replacement, but we'd also prefer to do minimal rewiring and plumbing work. Obviously we already have the three circuit...

    Hi All, I'm buying a home built in 2013 that uses a tankless Rinnai water heater. I know the current owner's never flushed or serviced the unit, and I'm trying to decide the best course of action. 1) The seller can hire a plumber - probably the cheapest they can find - to service the unit...

    Water heater Pressure Relief Valve open up

    Maybe two or three times a week my PRV discharges water. I have the PVC pipe running into a 5 gallon bucket so it doesn't run all over the floor. It fills the bucket up about ever 4-5 weeks. Is this bad, or merely doing what it is supposed to do? Thank-You

    Hard water + chloramine with tankless water heater

    I need a new water heater and I'm considering a tankless (on-demand) due to the long term cost/energy savings and space savings. A local plumber has recommended against it due to the water in town. I think he said the water has chloramine which causes problems with the tankless system. It's also...
