    Water Pump Installation

    I'm planning to get an electric water pump and DIY installation. Would appreciate some help from some sifus here who have done it before or have any idea how-to.

    1. What model do you recommend? I've heard of these brands before viz. Grundfos, Hitachi, Panasonic etc

    2. Degree of difficulty in fixing one, from scale of 1-10. Intend to instal it from water tank above ceiling. The water tank is sitting on a wooden platform.

    3. Where do I tap the electricity supply from? There is no 3-pin power point anywhere nearby.

    Thanks.

    Grundfos have one of the best reputation for industrial use, thats all I know but its not bulletproof. Its still prone to wear and tear. Panasonic seems much cheaper and economy model. You'd have to completely drain the water tank to do the piping works. You can use industrial strength PVC pipes and fittings (same as those used for mains water filter outside many homes). I hope you know how to glue up PVC pipes or else it'll leak. Best you sit down, plan and jot down exactly what PVC fittings, pipes, and consumables you need to do the job, unless you wanna run up n down the hardware store for bits and pieces. After glueing PVC pipes and fittings, leave to set for at least 8 hours before use. As for electrical supply, there may be conduit wiring or surface wiring running above the ceiling. You've to find one of those 13Amp power point circuit and tap from there above the ceiling. Actually you could like create another 13Amp socket above the ceiling. Of course you've to shut down your fuse box breaker before doing any electrical alterations. If not sure, PLEASE EMPLOY a competent electrician to do the job. Electric shocks ain't a pleasant encounter. What I did years ago was fix a couple of permanent flourecent lighting fittings within the attic so I can do work with light up there.

    I have a grundfos (bought for rm2600 display model) installed about 8 years ago. since then, I replaced the holding tank (rust and leaks). The grundfos replacement tank was so expensive (RM2800!) so I found another compatible tank for RM800. Their parts are very expensive but the motor is still running very well.

    I think I paid another Rm350 for installation and piping.
    It is worth it as we have been having hotel type showers for the whole family.

    The last time I had our Grundfos serviced, the technician had to use a pump on the installation to assist in the work - I do not know what he did but I do understand that we are dealing with a pump there and even if I knew the procedures involved, I would not invest in the necessary equipment to service my own Grundfos.

    Just like servicing the air-cond yourself where you would need to recharge the coolant, I cannot understand how this sort of job can be undertaken on a DIY basis. Even if I know how to recharge the refrigerant, I do not think it is economical to have the valves and refrigerant tank in my possession to get the job done

    I prefer to DIY my own aircon servicing as I'm fussy and prefer optimum performance from my own DIY plus the fun factor doing it all. Except for the type of refrigerant, the tools can also be used to service the car air-con. Did it on my Kancil recently.

    I am also trying to buy a pressure pump for my new house and was approached by h
    Hydro One with their Max flow pressure pump? Any comments or reviews on them?

    Tricky question to answer but try.
    1. Most if not all home water supply piping are installed WITHOUT any consideration for pumped water pressure, except the mains pipe to the tank or wherever that was intended to have water direct from mains. e.g. kitchen sink. GI pipes was the norm before PVC pipes came to existance. PVC pipes are much cheaper, easier and rapid to install. Glue up and ready to go. It doesn't take the very skilled to install simple routes.
    2. Most homes (depending on age) have either GI or normal duty PVC pipes from the tank down to the tap. Normal duty PVC may be able to withstand pump pressure but not guaranteed. Currently there's more to choose for HD class PVC pipes that are able to withstand higher pressures and as long as the installation is perfect and without defect, it'll withstand the service.
    3. Depending on age again, GI pipes are always prone to scaling, corrosion and reduction of internal diameter over the years. Say 10 years and the diameter reduction can be as much as half reduced. Come 20 years and its imperative to have them replaced.
    4. Many shun copper pipes simply because of cost, nothing else. Copper pipes are imperative for hot water pipes but its also because it doesn't scale or corrode like GI pipes. Again, quality of installation is everything for longivity.
    OK.. draw your own conclusion.

    Jutamind: You also need a 13 or 15Amp AC power at the pump location. Various pumps can be irritatingly noisy in operation depending on location. Consider these in due course.

    I had installed a pump for the shower heater at a 4th floor apartment before but hardly use it. Guess the pressure is ok.

    I guess I cleaned the filter at the basement often and use less fine filter. However, the water is dirty.

    Most of the time its the metal pipes that clogged up and I change it DIY.

    Nowadays some showers heater comes with built in pump.

    Installed one last year. Its the Panasonic model purchased from authorised Panashop..cheaper than other stores. Sorry, I DO NOT TRUST water heaters of other OEM brands, not that its much cheaper.
    My only grouse is wish it was stronger pressure, but that's personal preference.

    I have a Nocchi pump for my house installed by technicians. It took them quite a while to finish the installation as they have to ensure it does not leak. Thing to consider is whether the piping in your house can withstand the new water pressure. I had to change mine to copper pipes as the internal pipes was leaking. Also need to consider the location of the pump as it is generate some noise.

    When all is done you'll get shower experience like those in hotels.

    OK guys, Spotted an example of a Hitachi water pump installed above head at the front of USJ 9 Nivana Maju Banana Leaf restaurant as a mains water pump.
    Look out for the metered main water pipes at the front kaki 5 and its above head at the column. Looks good and not very noisy, perhaps the busy place drowns the pump noise.

    I am not sure which water pump is recommended, but I do know it is better to install a 1 way valve on the pump outlet (to prevent water return into pump) because it may cause water leakage.

    Its also called a "check valve". one of its purpose is to prevent a vacuum or air lock especially when there's sudden water supply disruption and running dry. As long as its fitted properly and securely, there's little chance of leakage, as with all plumbing fittings. Thats why quality installation is crucial.
