TS tryna kill himself it seems

Why is the gap so huge right after the elbow connector?

Why are the so many unnecessary connectors in between?

Why steel pipe and no fastener or clip holding in between joints?

topkek, 7 months, 2units spoilt and can ask if it's lousy

of course it is. when the thread started ktards already warned you about the absence of elcb in the water heater.

my water heater installed slightly above head level lor, hardly kena water when mandi, unless naughty son play n splash......no where so near the ceiling like TS lor.......either TS too tall or his ceiling too low.

last time I used joven too........ok lar, mine last 6 years then rosak.
If your case 7 months rosak 2 unit, you better check your electrical wire lor. Don't play play

An instant water heater can use both hot and cold pipes right?

Is an internal heater tank a good option for this type of water tank material?

Should be metal but not plastic right?

Your Joven also use plastic water tank?

But joven brand is plastic....


Thats why 7 months spoiled 2 units?

Instant water heaters only have one cold water inlet pipe. You regulate the water temperature by toggling the set temperature switch/knob.

The isolation valve is located at the inlet of the heater. The outlet of heater is not supposed to have any valve to avoid over pressuring the heater and cause internal leakage.

Also, you're not supposed to use steel hose or pipe to connect to the heater to reduce risk of electrocution.

The heating coils are not supposed to be subjected to any pressure by having the water stop valve at the inlet and no valve at the outlet.
I highly suspect TS' connected his instant heater the way storage heaters are connected. The difference between them is storage heaters have pressure relief valve and instant heaters don't (or I've yet to see any). So any overpressure in instant heaters will cause internal leakage as in TS' case.

There is no different in what model.

Tell me more detail where is the exact the leak.

I probably can understand why it leak.

Need a registered (with BCA) electrician not just any joker with a pair of pliers

I think Panasonic brand water heaters have the valve you mentioned.

But kesian Joven brand do not have the valve.

Does this valve reduce the pressure from the main water supply pipe of the water company?

Some water companies supply water to our house pipes at too high a pressure.

But normal what brand water heater also have this valve to control water volume right?

No need. Pana push start just press the big button to on/off water and heater together gether.
Water valve is there but hardly touch. TBH, water valve-sahaja (no push start) is B40 model.



Topkek

See the piping go huru hara all over also likely overtightened AF and cracked the inlet plastic connector of the WH

where is the pipe joint leak? It is from the hot water outlet joint?

Exactly at where?

It controls water VOLUME not PRESSURE.
If there is a problem with extreme pressure, make a report on LifeSG

My house in Malaysia also uses a Panasonic water heater, and we've had it for 9 years already.

However, I need to close the volume switch every time after pressing the big button on the Panasonic water heater.

If I don't do this, water keeps coming out even after pressing the big button.


The same thing happens when I want to take a bath.

If I don't open the water volume switch and only press the big button of panasonic water heater, no water will supply to the water heater, and it will make a noisy sound due to high pressure.



Why like that?


This Joven water heater is at singapore house.
