Water Pump

[StevieAus]

Hi I am seeking advice in relation to a recommended water pump available in Thailand and from a reputable maufacturer for the following situation.

I have an underground room which due to not being properly sealed during construction experiences water seepage during some wet seasons.

The problem has been isolated to one area and it has been suggested that a sump be created and an automatic pump installed not in the sump but outside above ground

The amount of water would probably be a few liters over a 24 hour period depending on the season 

It would require a vertical lift of approx 2.3 meters and horizontal lift of an additional approx 3.5 meters.

If this isn’t practical any other suggestion would be welcome as I have no expertise in this area

Thanks in advance.

My guess is it is not so easy to find a self priming pump for just a few liters/24hour. I should place the pump in the sump.

 

Surge for a "bilge pump", something like this:   https://www.lazada.co.th/products/linemart-12-submersible-1100gph-i3414844-s4159348.html?spm=a2o4m.searchlist.list.15.129f4a821UM5H9&search=1

 

They are also available with a level switch, or you can make yourself a level switch.

Thanks for your response my preference was for the type of pump you suggest however we cannot really make the sump deep enough maybe back to the drawing board

For the amount of money you would be spending on a pump, which is firefighting, how about looking at some sort of tanking, like sika/Lanko rendering around the problem walls and floor.

If space permits, a secondary wall lined with visqueen. 

Just throwing out options.

 

My son had a kitchen in the basement of his house, against my advice and the rest of the family to buy the house he was assured that the sump pump takes care of everything. It was working constantly clearing ground water until the day someone pulled out the plug thinking it was the microwave.

 

kitchen flooded, insurance claim, lots of trades in to make good, but a good learning experience for him.…...

the point being, we have many power cuts here so a pump cannot be relied on 100%

Thanks for your response and suggestions, we have carried out only recently what you have said about the sealing aspect using perhaps different products.

We engaged someone who seems to have expertise in this area but only in the last few days found the source of the problem behind a false wall

The idea of the pump is probably my paranoia as this guy seems to think it’s not necessary.

One lesson to be learned from all of this is maybe “ Never build below ground”

again again for your response and suggestions it’s apppreciated

You are aware that pump is about the size of a Tylenol container?  They are tiny - but not sure how high they can pump and as said an activation switch would be required to start/stop when sump fills.  Normal 220v sump pumps are also available here and pump down to about 1cm water level so would not need much of a sump.

Lots of questions here, such as where the water is coming from, floor or a particular wall?

How the room is finished, such as drywall or conrete and render? What is to say the water ingress will stay in the present location and not creep elsewhere? ie during flooding and water table rising..(if you block it then it will just go somewhere else)

Can drains be put outside to make a seepage away from the room or is the outside built up and not accessible?

 

Basement drainage can be a costly endeavour and worth taking the time to do the research the first time....
