= The water works is GE-WW 9041 is in principle a good Pumoe. The capacity is very large, which is why you should also have the right application for the pump. Convinced processing, everything seems robust finish, the equipment is virtually complete and the power quite low in relation to the pump capacity. However, the pump has no protection against dry running, which can result in the interior in the worst case to overheating and boiling of the residual water, injuries are thereby not excluded. Einhell has but then reacts very professional and adds the pump appropriate warnings at the not yet inserts my device. There is also a deduction, but because of the very good service and good pumping capacity is sufficient even for four stars. With dry run protection it would become 5.
-------------------------------------------------- ------
Now for the details:
Processing & first impression:
The water works is a 9041 house number, which can be seen already on the carton size. With 64cm height (plus space required for the upward pressure connection) I still have it just got into Pumpenhäußchen. My old Einhell 5537 looks like a toy next to it. Ultimately, the domestic water supply from a 9041 Einhell pump was connected to the water drain plug of 20 liters accumulator via a pressure hose. The intermediate article additionally includes another pressure gauge and is in the pump, as with the Einhell pumps typically, a fairly useful prefilter integrated, so that you do this not once again have to buy extra (for me at that time to grab one of the reasons for Einhell) ,
The pump housing is made of robust plastic and looks well made with good feel. The handle is rubber coated and the pressure vessel has a steel surface (as well as the silver part on the pump housing). The feet are made of plastic and have pre-drilled holes for fixing to the ground. Everything at the pump is very solid and I have some pumps such as seen with less massive pressure hoses that were not much cheaper. Also details we convince greased seals in Berich the prefilter. The female thread (G 1 / 33,3mm) for pressure and suction hose are made of stainless steel (here there are still manufacturers that rely on plastic in the area).
The pump, in addition to a pressure switch also integrates a temperature monitor which switches off the pump in case of overheating. As accessories Einhell with the pump at a key to open the Vorfilterdeckels that one also should not be embarrassed, because this quite heavy rises over time.
Small note still for connecting cable (may be relevant for the site yes): This is 1.60 meters long.
From the exterior ago the pump can convince definitely.
In-Shutdown:
To connect normally adapter with G 1 thread required in addition. Due to the large height above ground of 56 cm (center suction pipe connection), it is advisable to use an angle adapter for the suction hose, if you want to promote vertical water (eg from a well). It is good that the terminal protrudes so far above the rest of the case that the suction hose directly degree angle can be passed down in 90. Einhell recommends a suction hose with a minimum dimension of 3/4 inch. Also on the pressure side should be used to get the maximum pumping capacity according to the instructions a 3/4 inch hose. I thereto the professional system of Gardena connected, which operates two circles of a sprinkler system. Although the pump has a check valve, a check valve should be used in the suction hose in addition, because otherwise the pump again idles. Is this the well pipe no capacity, a corresponding valve can also be used between the pump and suction hose, works just as well, if there are no leaks.
The pump must be pre-filled to suck water. Einhell has a bleed screw for this purpose in addition to the pressure port placed, only with a screwdriver or coin to open, however (which is in all Einhell pumps so). Why has the screw not designed as the water drain plug, is beyond me, because these can be easily opened by hand. Alternatively you can also fill but via the pressure connection of water and it does not take much to move the pump to work. Before starting operation should still check the air pressure of the air bubble in the pressure vessel, it should be 1.5 bar. A simple hand pump with pressure gauge and car valve is sufficient for this purpose.
After the pump ran on smoothly and was expected to be completely sealed. The transparent filter cover can be seen when the water is drawn (and you can hear it).
All in all not rocket science, can be easily and intuitively operate.
Pump Performance & operation:
This is already enormous. The suction is carried out at me from about 7 meters deep, which handled the pump easily. On the pressure side, the pump was able to run my sprinklers with more than 2.5 bar pressure and at the same time to fill the accumulator further or next to the sprinklers also to use a spray hose, that was unthinkable with my old Einhell. Recommended by Einhell 3/4 inch pressure connection should therefore also be really used, otherwise just irritates you not from the pump and you could also easily a 1 inch tube connect with the performance.
In principle, the pump switches at 3 bar pressure from, serving the consumer from the accumulator until the memory is less than the pressure of 1.5 bar. Went smoothly in operation and reliable. However, one should consider when buying that the machine very quickly if there is insufficient consumption begins clocking due to the high flow rate, ie it switches off again and on again. Only with correspondingly large decrease it ran continuously. Excessive cycling of the life of the pump fragrances not be conducive. But this is not a shortcoming of the pump but corresponds to the domestic water supply principle. Who wants to have a continuous pump running at any order quantity, will have to look for a home water dispensers without accumulator.
A change of the shift values for the pressure accumulator is not provided in the way of the pump.
Small Wehrmutstropen in operation was the strong shaking manometer. While it was the pressure reliably, but the needle was trembling heavily while the pressure was built up, I've seen better.
The actual power was in the way when operating 872 watts.
The pre-filter is more than sufficient and there is no need for additional filter. Larger foreign bodies remain easily hang in the filter and can be easily washed off. As I said, it may be necessary to open the filter cover to use the key provided that the lid like something serious comes up to. Should turn one way, using only hand-tight and not merely the key, otherwise you can not get to the filter in the worst case.
A pump runaway, the pump does not, however, what can be painful as I unfortunately had to find in the worst case. When running dry, the remaining water is heated in the pump above the boiling point and can escape when opening the prefilter with pressure, scalding are the result. One should open after shutting down not miss the pre-filter, since under pressure, can shoot out of hot water when the pump is running inadvertently. Einhell has responded professionally upon notice to and with the pump in the future in appropriate warnings and showed repeated here a good, courteous service for the purpose of product improvement.
Volume:
The performance is achieved through a slightly higher volume. Einhell are those with 91 db and the smartphone app showed 88 db in intake process, so that the statement appears consistent. I have integrated the pump in a wooden house, so that the volume not as occurs in appearance, on a quiet summer evening, the noise can be distracting but quite. Smaller, less powerful pumps spent about 10 dB less noise, which can be clearly noted yet.
Shelf life:
At the 9041 myself I can not say of course about the durability, the review will complement but from time to time. To Einhell pumps in general I have but few empirical values. From 5 Einhell pumps the neighborhood (all different types) has not yet had recorded a loss in the last two years. All work despite frequent operation in the summer still perfectly. Only the suction of Einhell (particularly simple) do not have the best quality and although Einhell is very customer friendly in replacement I'd rather grab here to Gardena hoses.
Conclusion:
A very powerful domestic water supply, which even at higher suction lifts a considerable amount of water promotes, no comparison to my smaller Einhell 5537th It can easily several consumers are operated simultaneously. The processing can be described as very good, everything looks robust, meticulously crafted and has a high quality feel. The great advantage of Einhell pumps is the integrated pre-filter which performs good services. So you need to start next pump connection adapter (double thread G1) only a non-return valve for the suction hose. The consumption of the pump is more than acceptable and only slightly higher operating volume that something unfavorable bleed screw, and the trembling pressure gauge must be hinnnehmen in relation to capacity than small flaw. Larger shortcomings is the lack of protection against dry running, which can result in chain of unfortunate circumstances for hot water outlet. Einhell but here improved. Therefore, even 4 star for an otherwise good pump that allows you to unintentional running but should be careful.
