I using this...Grundfos ch2-50pc. Not sure how many HP.

I am going to change it to a smaller pump.

Anyone got any review/comments for the following pump?

Tsunami JLM 200A

and

Panasonic A130 Jack

Thanks,

I have a situation which just recently happened.

I turn on a water outlet and very low water pressure comes from that outlet. in other words, the pump didn't activate. when i turn on another water outlet, the pump activates and I start getting good pressure form both outlets. each time i have to open another outlet to activate the pump ( it takes 2 outlets to be opened to activate the pump).

This happens in all locations in my house. any idea how to solve this, is this a pump problem, if yes which part of the pump has malfunctioned? I don't think it's the motor as the pump still works, albeit, with the workaround method above.

better to install scala2 before or after a water filters？

piping issue?

seem like have to get a plumber to check what is the issue.

I don't think so. Pump is not being triggered by the water flow. It takes any two outlets to activate the pump.

Always after filters and placed after tangki if you're in landed dwelling. You want the pump protected. Most important criteria for the filter must be able to cut out mud, silt, rust. If you use those stone and sand media, protect it further with another layer of 10 micron pleated filter before it enters the pump. With membrane or 3M AP902 that won't be necessary as it is already protected at point of entry.

noted，thank

another possible issue is air trapped in your water supply pipe.

pump has to be installed before water filter.

1) THen u will have strong pressure to backwash the filter
2) If after filter, the filter will reduce incoming pressure further, hence less water for the pump to boost

I thought it could be air as well.

But it happens in all outlets, from my outside porch garden faucet right to the bathrooms above.

My washing machine returns low water pressure error due to this.

Not sure what’s the reason.

the pump controller spoil d, get some1 to check. If under warranty, quickly call the customer service

I am using 3M outdoor and indoor water filter. Good thing is no need to backwash.

I am using storage heater for all rooms upstairs with grundfos water pump. So far so good.

Any thoughts on this Hitachi water pump?

I stay in single storey landed with 2 bathrooms, need water pump mainly for rain shower and no loss of pressure when other outlet being used (washing machine, flush toilet, etc)

Any one can recommend me a water pump installer? I go thru 3 Pedrollo Brand supplier, they didnt do the installer, they said nows a day many plumber handwork not nice, many problems. Can anyone recommend me one good installer?

By the way is the Pedrollo 4CPm 100 or 3CPm 60 suitable for the house that have 3 bathroom at the 2nd floor, and 0 bathroom on the 1st floor, 1 bathroom (kitchen) at ground floor. 3 people living.

Thanks zheilwane. Already called the CS, now waiting for them to come.
Unfortunately it’s already more than 2years, so out of warranty
Not sure how much it cost to fix the controller. I’ll soon know!

Get one that services at least 6-7 outlets then. Ensure anti vibration mat are installed under the pump. This one looks better with one extra feature.

Also, ensure there's adequate filtration before the pump ideally after (point of entry) the water meter to filter out the pump killers: sand rust silt mud. If this is done then ensure tangki is washed thoroughly first to get rid of any resident pump killing matter before plumber installs the pump.

Thanks! Whats the reason for the anti vibration mat?

Sums it up pretty much in principle. The vibration will be transmitted outwards from where the pump is located. If not attenuated, it might be nuisance at best or the pump night be prone to "walking" or be transmitted along the piping. For that where piping is known to hit the other part of the roof support, place a small piece of anti vibration mat (cut to size) in between to shield it from this tendency.

Note: everyone upstairs might still hear the pump's soft humming when it's operating. That can't be avoided but if your plumber has done something marvellous that reduced the humming such that the only time you're aware that it's operating is when you're directly under it, do share. I want to know how also.
