looks like ABS pipes to me

When you bypassed all your toilets what is the use of the tank? Your tank water will be dead. Some dead water will get to your toilet and wash you! And when water supply stops you get all the dead water to your toilets and you bath with it and get sick brushing your teeth!!!

Stagnant water keep too long is no good, lots of small friends inside.

, i've no idea what that bolded statement is trying to say

other than stagnant water = shit

water needs to move in the tank/cycled out.. best is as much as possible and if not 2 flushes a day.. so new water with chlorine can come in and kill what ever germs that is in there

just curious how long can the chlorine last ? 2 days ?

Over night will be clear

Why the plumber never advise such a problem will arise if want to bypass? Can't blame on the owner with less experience.

Aiyo Jin, Our friend started the thread calling bathroom as toilet. There is no two pipes to one bathroom ok unless there is a hot pipe and he is talking about bypasses not a new pipe one to toilet one to shower and basin. If I say bathroom he might not understand. So the statement goes like this, "Some dead water will get to your toilet (bathroom) and wash you!".

When direct main pressure is higher than tank water pressure there will be no water coming out of the tank as he experienced that after the bypass the presuure increased. Unless water supply is interrrupted than only the tank water can flow to "toilets".

When the water stays too long like weeks or months without constant supply of chlorine, at first there will be some bacteria getting in then parasite and any other micro organism. These bacteria are aerobic bacteria get in (how they get in I dont know but they will sure get in), aerobic bacteria live when there are oxygen and breakdown any dead organic materials that die there. Why do you think there are dead things there? These things were killed by chlorine in the dam, in the pipe, in the resorvior then carried to the tank. These bacteria will convert the dead things which is ammonia into nitrite and into nitrate and when there is nothing for them to eat they also die and oxygen level get very low. When there are too much of nitrate in the water algae will grow. Believe me you will see algae in such condition though lack of sun light. Some how some light get in the tank from the roof unless it is total darkness. Then algae consume huge oxygen and the tank will be of little or no oxygen except on the surface, any present will be taken up by the algae and the nitrate will be converted to nitrogen. With the absent of oxygen at the bottom tank anaerobic bateria (bacteria that live with little or no present of oxygen) will then consume any nitrate left back to nitrite and into some other things then into nitrogen and other foul gases the smelly longkang (drain) with stagnant water kind of smell, called dead water. The smell are like rotten dead animal or plant kind of smell as all these processes take place. So, you will wash yourself with these water when main pressure is low or stop supplies.

Do you also know that never use tank water for cooking and drinking? That is why kitchen is always supplied with main direct water pipe and never from tanki !!! For the same reason. By boiling you kill the bacteria but not the poison produces by the bacteria. If you dont boil sure you get stomachache with just one glass for tank that has been kept for too long. drinking longkang water

Can put some fish inside;-)

For people who seen well before, ever notice why a Live fish is put in the well?

Let's me finish it off. When there is no water supplies the tank water is used. When water supplies resume, the chlorinated water fills the tank and kills all the bacteria and algae. They die and new bac and algae get in and the roting process continue....until such time water supply stops again.

They tell you they have been doing this many times, no complaints and owners are happy due to higher water pressure. Blame the school. Only teaches us how to count, to write and to read. You dont get to study this even until university depending on the subject you take.

Also, think again if you use multi carbon cartridges. Bacteria live there too. Boil your water. And best get filter come with UV. UV will kill any living organism from your water dispenser/filter. In US you have to have UV.

Best is to connect your water tank water to washing machine. Put it in good use.

Well, the bypass is not actually 100% bypass as u can see in the pic there's the spring loaded one way valve which actually allows the water from the tank to flow out to the toilets @ bathrooms upstairs. This is to ensure if there's no water supply, the toilets @ bathrooms still has water supply from the tank .

The toilet downstair which is frequently being used as well gets its supply direct from the tank. Furthermore the tank comes equipped with a drain valve in case for washing the tank.

can pm me the best price for CH2 and CH4? Btw, i read from the website that PT is far more quieter compare to CH2. is it true?

who is zean? and how you come to choose CM3, instead of the normal CH2? care to share more?

so what do you advise now? mine is a double storey terrace house.

Added on June 17, 2012, 12:34 amso you ended up buying which water pump?

PC & PT pumps have the same noise level as they are using the same pump but PT pumps have lesser vibration as the PT can absorb some vibration and the weight of the PT will dampen the vibration as well.

CH2 has been discontinued and replaced with CM pump.

Who is Zean?
Zean = Zheilwane

If you wan to get a quiet pump, constant pressure and lesser water hammering, go for UNI E but it is double the price of normal PC pump.

When you get heavy or lots of hammer sound is because of bad installation.not because of pump.

+1 ...

Some houses do not have water hammering noise at all, some are very noisy. If it is the pump's problem, every1 should have water hammering, so it is quite true that water hammering is due to poor installation but water pumps like UNI E start slow and stop slow could reduce water hammering

but the price for the uni-e

either fix the hammering by fixing the installation of the pipes and the pump

i've came across some topics where by the hammer can also be-caused by the tap/washer thinggy

how true is that ?

can you pm me the price of this Uni E and the CM pump? So in your opinion, CM is good enough?

Hammering sound no longer happen after I use it for few times. This just happen when I first installed & tested it, so far so good.

Zean, thx for your hospitality last Saturday, couldn't get more from you since tight budget...

Hi All,

Sorry for tapping on Grundfos water pump thread.

I'll like to find out, anyone has experience with Panasonic Water booster pump.

Example A130 JXC and A130 JTX

What is the different between the 2 model?

I was being quote JXC @ RM350 and JTX @ RM400

plumber is charging me RM400 for workmanship to install the pump and addition piping for double story semi d. Is the charging reasonable?
