electric driven Well Pumps

Post by simmo on Tue Jul 16, 2013 2:42 pm

Hi folks
On the old forum a lady spoke about a well pump system she and her husband had installed and posted photo's of the system. I contacted her about the system and was waiting for further details but alas nothing. Does anyone have a well pump system by any chance and if so willing to share info on it.
I have tried to rig one up myself but the pump i have as only a 6mtr lift and i need about four times the lift  power.

Apologies simmo, 'twas I that you refer too. I am very sorry for the delay in replying non reply, been really snowed under with work & more work, then Glasto, then a couple of Hyde Park do's, it goes on and on. Remind me again what you want and this time I will apply myself properly to the task.

Hi Greetings Le Dolly
Yes ref the old message. I asked if you could give me a ball park figure as regards cost of your well pumping system.The type of pump you used and from what depth you pump water from.
Thanks

We rely entirely on a well for our water as we're completely off grid. Well not quite entirely as we collect rainwater which we use for loo flushing and non-domestic needs.

The pump fills a header tank in the loft much like a traditional British cold water system and, with some electronic tinkering, the header tank fills automatically when the water level in the tank drops to a specified level. Bear in mind that if you want any sort of automation it is not practical to use a single float switch in the header tank to operate the pump, you need two and a system of ratcheted relays. I can explain in more detail if you want the technicalities. It's an entirely DIY system so the cost is minimal.

The most expensive items were the submersible pump for which, from memory, we paid about £250 and the hose from the well to the header tank. We used heavy duty MDPE pipe (the typical blue water pipes you see) and because we needed over 100 metres of the stuff it cost us about £100 from memory. Both the pump and the pipe came from British stockists although you can easily buy pipe fittings at any brico.

I guess the system would depend on what you are trying to do. Is it to be a main or standalone water system (which is what ours is) or is it to supplement a mains water system? If the former then be prepared to spend good money on the right pump. Ours is now about 5 years old and has never let us down. If it's just for back-up purposes then you can probably use something cheaper but it must still be able to lift the water to the right height. I'd allow some spare capacity if you can afford it.

If you've got any specific questions please feel free to ask here or PM me.

Hello Simmo, our system comprises of a fully submersible pump, in stainless and a 100lt pressure vessel with all the ancillaries necessary to couple it all together.
The water is pumped from 17mts down to the vessel which pressurises it and then on to a manifold where the water is distributed to the boiler for hot water and heating and into a cold supply for washing, washing machine, WC's, bath/showers, steam oven and automatic garden watering/drip feeds(essential at the moment) and hose-pipes. At the manifold is a turnover valve should there be a need to return to a mains water supply. A separate mains water supply is directed to three basins and the kitchen sink, via triple entry taps, for drinking water for the OH and feeble willed visitors.
The most important, in my view, item is the pump and it's quality. You must buy one that is fit for the purpose and good quality fittings for any part that is to remain submerged. Our pump has a net static head (vertical lift) (hauteur de refoulement) of 60mts, that gives plenty of spare capacity. Remember to fit the pump with a rot proof rope or wire hawser, before you lower the pump into the well.Laughing  The vessel is fitted with a self-regulating pressure switch which is set to 2.5 bar and that gives a really good pressure at the taps and particularly at the shower heads, almost enough to give one a headache and will fill a bath very quickly. It also retains the pressure at the third floor level.
I cannot remember the manufacturer of the pump, but I seem to remember that it cost around 2-250€, Brico-Dépôt offer one for just short of 150€, but I would shy away from recommending it, as I have no knowledge of it's quality. http://www.bricodepot.fr/chateauroux/pompe-de-puits-1-000-w-/prod30453/
The pressure vessel is from Varem, http://www.varem.it/index.asp?sel_lingua=FL_DLingua02 and cost about 270€, but we did get a very hefty discount with buying as artisans. The pressure switch, connectors and pipework came in under another 300€.
To us it was a 'no-brainer' decision to take this route, over the five years the system has been in place, we have saved on the usage and cost of approximately 375³m per year of mains water.

WE have a submersed well pump that we had put in 9 years ago and feeds a pressurised tank in the cellar, like you Le Dolly we have saved lots on water bills. Should they be serviced? WE have never even looked at it since it was installed.

Should they be serviced? To be honest, I don't know. Before the thing was lowered into it's new home I do have a recollection of looking for a service plate/aperture on the pump, but I cannot remember one, so I presume no. Mind you a great deal of substances and beer has been consumed since then so it is anybodies guess.confused  Should they be looked at? Ours is situated under the floor of one of our tenants' salon, hardly readily accessible and what are you going to see? I am minded to to believe if it is working, all well(no pun) & good, when it fails, drag it up and repair/replace it.

electric well pump

Post by simmo on Wed Jul 17, 2013 9:32 pm

Hi folks Simmo again.
We have a 25mtr deep well in our front garden and it has water at 20mtrs and is in good condition. we have the pipe work to go down it and a electric supply near by plus an electrical cable, all i need is a good pump to lift the water to the surface. The idea being plug in switch on and fill water cans to water flowers.
So it's really the name of a pump able to lift from that depth or pump supplyer that i need. thanks also for all the info that folks have sent so far.
Simmo in the Correze.
PS The pump mentioned by Le-dolly for 149 euros from the Brico store looks to be the one with 55 mtrs of lift it should do the trick .I think i'll give it a go and keep you all posted.
