Hope it was OK - he is a friend! Re: Cost to fit a water tank and pump to a house. 3Oct 02, 2008 7:19 am I suppose it depends on how much work he put into it and what he paid for. You didnt mention if he supplied the materials and parts. Did he trench in the downpipes to the tank, if he did then it sounds like a good price.
We paid half that, just to connect our pump to the tank and tank top up. (I had to buy all the parts and pipe fittings for him) Re: Cost to fit a water tank and pump to a house. 4Oct 03, 2008 9:09 pm Yes he supplied all parts and materials needed. He didn't dig trenches for downpipes - tank was positioned right under one downpipe which fed directly in. 2nd inlet from other side of roof was a big white plastic tube thingy, but as we were high up off the ground on stumps, it was sort of strapped to the underneath of the floor if that makes sense. He dug for and installed 2 taps. We had dual overflow - either going to storm water, or down to extra agi pipe in garden - hubby had to dig that trench, but it was only about 5m long. Re: Cost to fit a water tank and pump to a house. 5Oct 04, 2008 6:28 pm If he didnt buy the pump and didnt bury the pipes then its probably average, especially when you compare it to what we were charged for. If your hubby did it (except for the elec of course) it may have saved you about 30%, but for some people it may not be worth the risk of getting it wrong. As long as its quality, I always say Re: Cost to fit a water tank and pump to a house. 6Oct 05, 2008 1:04 pm Is this a new house or old one?
I can imagine it should base on how much time is needed. I would suggest to get a few quotes and get more details. Also just a wild thought, might need to know what sort of warranty/service they provide, as if something goes wrong, say X days later at 2 am lots of water comes out from your toilet, do they provide 24x7 service?? Re: Cost to fit a water tank and pump to a house. 7Oct 05, 2008 9:00 pm There are a heap of variables, so I can only make some suggestions, and guesses to ive you some ideas. This wont include labour, and minor things like pipe sealants and silicon etc. I have 90mm PVC pipe. remember he will get trade, so I can only quote retail.
From the roof you will have your downpipes. Thre may be afitting to go from the downpipe to the PVC pipe, around $5-8 each. From there PVC pipe is between $35-50 per 4-6 mtere lenght.ounds vague but it depends on where you get this stuff as to the lengths and prices. Elbows are about $2-4 each as are joiners. T pieces up to $10. That gets the water to the tank. Here is where it can start to get expensive, depending on what was used. But first a minor explanation. Most pumps are pressure sensing, ie they sense a drop in pressure in the outlet end - usually due to you turning on a tap, or a pipe pursting. When a pump senses this, it activates and brings up the pressure. When you turn off the tap, it will build up the pressure, sense it is back to a presurised state, and stop the pump. What this means is that the plumbing from the pump to the tap is always under some pressure. I hope the used a good quality pipe, that is pressure rated. it should be black, with a blue stripe down it. This stuff is designed to hold the pressure, where as your 19mm or 25mm black sprinkler and home garden tubing is not. On a Bunnings price, I think it was about $80 per 50m, and alot more for lesser lengths. The 90 degree corners are about $10, the T pieces are about $15. Back to the Tank. You will prob have a 1 inch outlet, which should have a valve on it. About $15 each. This wil go to a joiner or two, or an elbow into the above described black and blue pipe. again about $15-20 per joiner depending on shape and pipe size. You will also need an adaptor to take you from the tubing to the pump inlet hole, and another to go from the outlet to the same pipe off to the tap. Then you will need some type of tap, whether on a stem, or wall mounted. Its fairly ague, as suggested some photos or some other sin the know might be able to help. If anyone can give a better idea, off you go, this is only what I did for my 8,000 litres I have now. If I can find some photos I will post. Adrian B 18 90470 Building Standards; Getting It Right! Thank you for the generous offer. I need to get the plumber out to give me an explanation. As mentioned I haven't seen any rain water discharge from pipes 1& 3. It… 7 10808 |
