cheap pump, small flow rate , frequent start stop quite annoying.

if Rm400 for installation only= expensive,

additional piping for the pump installation or @ other area?

RM400 installation is expensive? I tot Zean also mentioned it's around that price?

I also got RM400 water pump installation with direct water bypass after I show my plumber the installation diagram I got from Zean. Before this he quoted me RM300.

Hi skng03,

Thanks for your prompt replied, according to the plumber, he'll be doing a direct pipe to master's room toilet, and addition pipe to the water storage tank on the roof (believe to fill up the storage tank water as fast as possible). other then that i'll to get him to install an additional tap at the back of the house.

I'm also considering Hitachi pump as well, being offer for RM700, but i do not know whether if it is 100gp or 180gp series. The seller is from JB Hardware provision store, he can do postage for rm30. But the issue is im from Klang, can't find dealer dealing with Hitachi pump other than Panasonic which is located in meru.

Anyone got any shop to recommend me for the above brand pump or reliable plumper that doesn't charge an arm or leg.

Thank you

These pumps are cheap and durable. But as it is the continueous on/off of the pump is too noisy to have it in the house. When it cannot be installed in the house due to the noise you cannot have it on the roof but outside the house. That means the pressure from ground to the roof is lost especially so it it is double storey.

Unlike Grundfos pump you can install on the roof/celing. The pressure from top to the bathroom is not lost but even stronger as it comes down with gravity assist. When pumps are installed at ground it loses its head/pressure due to height/gravity.

When choosing a pump, you have to know what you want it for? What is the objective, what you want to achieve? You got semi-d 2 storey you should go for high range pump, not because cheap pumps are not good, because you can afford for luxury. Drive expensive car with re-treaded tires?

The plumbling charge is reasonably cheap for double story semi-d.

You can get Hitachi water pump in Klang too, so far the nearest I got is few hardware shops around Econsave Jalan Kebun, Klang.

The installation diagram of Grundfos water pump with water bypass. You can get the same as well in Hitachi water pump brochure.

Dear stevie8,

Appreciated your detail explanation, i though of the noise issue, thus i am planning to set up the pump around garage, as much as i would like to own a grunfos pump, my budget doesn't allow me to stretch deep enough.

Thanks

rm400 to install the pump only is expensive, imagine just cut off the main pipe from water tank, connect to pump inlet and outlet with few fitting

zean's diagram include additional non return valve / by pass, rm400 is reasaonale

I don't see it cheap when it come with such a famous brand like hitachi and panasonic. Unless china don't no what brand. There is always a way to work around to reduce the way you 1. If you DIY enough.

You can mount it on the roof. To minimise the vibrate, place an 4pcs antivibration leg or rubber matt at the pump bottom. You can put a cover with neoprene inside to reduce the noise.

You can put a tank at the pump line to reduce the on/off frequent of the pump.

If all this add up and still cheaper than the expensive pump, why not.

The installation just for the pump of course is expensive but he said additional piping to a semi-d. Of course Ozak is a DIYer anything more than material cost is expensive

Puting a tank yes but tank costs money. RM200 maybe but that is a very good idea. I will do that too.

cthardware @ tmn mayang/pj that side got sell hitachi pump ...

700 bux i think its the 180gp... cause i checked out the pricing last year... it was 680...

How do you compare Hitachi and Panasonic? Price vs Specification? Any info?

didnt do any comparison between hitachi vs panasonic..

can't seem to find anybody selling panasonic one when i was doing my r&d..

i compared my hitachi with grundfos.. lol

i found that that.. grundfos is overkill for my usage so i opt for hitachi

What is your spec consideration when choosing a pump?

power consumption , pumping rate(1 pump supports 6 open tap and that sort)

What is the model no? How it works? You on the tap the pump switch on itself and off and on and off? Or you turn the tap it on and off the tap it off.

So the pumping rate should be liter perminute. Is there a guide average how many liter perminute should the pump deliver?

Let say a shower bath, how many l/min can I get a nice bath?

shower head flow normally <10L/m, rain shower 9-14 L/m, eco friendly/ save water type <= 9L/m

Thanks. I can use this guide to choose a pump.

noob question..the pump will go after the tank outlet or from the solar outlet?

Just completed installed Pedrollo (Italy band), surprisingly very quiet. Finger cross. Although hardly mentioned in the forum, but happy to know it fr the water pump seller who keep on insisting recommend me this brand. Earlier only tot of getting Grundfos for the reason reliability and quietness. Till give a try on this brand. Was happy and also within my budget.
