Is there a lack of a bypass pipe connected to the hot water outlet pipe or the cold water inlet pipe?


Because now just 3 months,this heater spoiled again.


Big leaking issue.

If this happen 2nd time, the heater shouldn't be use anymore. The plastic pipe is weak and cannot stand the water pressure.

Got to check the actual water pressure. Find a better spec heater that can stand the pressure.

Normally the electrician doing this is to makesure nobody ON the switch when he doing the work.

If somebody ON the switch, the RCD trip and save the guy working on the site.

It's an old traditional way safety. Doesn't write in the text book.

It is because safety.


The shower head should not spray water accidentally onto the water heater's outer surface.

Is your house's water heater installed very low?

why do you need a bypass?

No need bypass, this is not process cooling.
Replace the heater and don't use steel pipe connector use PVC instead.

Add one manual valve for cold water.

1) Why can't we use a steel pipe connector and instead use a PVC pipe?

2) Do you work in the HVAC (Heating, Ventilation, and Air Conditioning) sector?

Actually, some tenants always leave the switch on and never turn it off, even when the water heater is already leaking.

3) If I add one more valve for cold water pipe, will I need to open two valves when I bathe?

4)Do you want to decrease the pressure by adding one more valve?

Once it join together, if it trip, it will trip.

2nd, heater wiring are individual and no looping.

Is this joven brand too lousy?

I plan to change to panasonic brand



In 7 months,2 units spoiled.

why all images are too large?

I think the hot/cold pipings are for storage heater. Apasal install instant heater pulak?

Also, the shut off valve stops the water inlet or water outlet? If water outlet, it's dangerous as instant heaters iinm don't have pressure relief valve.
