My good old 20 years old National WH (Air Bubble Jet series with the elephant mascot) started to give problem. When I press the start/stop button to turn off the water, the water doesn't immediately stop, but will continue to flow for like 5-10s before it stop, quite annoying. Any idea what went wrong?

If need to replace, what is the recommended most reliable WH? Judging from my experience with National, I guess Pana? And which model (prefer with pump)? TBH I haven't used any other brands before like Joven, Alpha, Midea etc.

I think I have same model. National DH-311M? Used to be like that but these days, water doesn't even stop unless I cut off/turn off water supply laugh.gif

Apart from above, the ELCB light(green LED) doesn't even light up these days. But when I push the ELCB test button, that thing seems like it's working because water from warm/hot turns cold.

Please advise.

Greetings, peeps. Need to replace this ancient stuff(20 years already) tongue.gif
Any recommendations? Actually this old-timer still kicking well, heating power is sufficient 3.3kW(not living in highland), it just lacks booster pump. Need to replace it with a new one with same/superior durability and excellent pump. Don't really mind if it's AC (noisy) or DC(silent) as long as the big boss enjoy her shower time. Please help icon_question.gif

Just get the Panasonic with pump. Should do the trick. It’ll have the same push to on/off the unit with water flow, which you are used to. No need to fuss around with the water flow tap.

Any idea or number I should look at the pump spec? Is there something like minimum water pressure pump worth buying or don't buy at all thinggy?
