Hi all ,
Just wanna ask .. Can stainless steel water tank be install outside the house , at the back and on the ground ?It is a terrace house with extended kitchen. Can the tank install outside the kitchen ?
Does the tank come with fully sealed lid ? So as to prevent naughty neighbour kids from throwing foreign items into the tank ?
Thanks
Uncommon as they are big and normally not done unless there ample space like a big back yard that none of the amenities at the back is affected or you dont mind losing that space as it's compensated for elsewhere esp drying.
A concrete slab base needs to support the tank to prevent it sinking unevenly due to ground settlement plus to safeguard against corrosion from soil. Plumbing need to be rerouted from the internal supply piping to the roof. Outlet pressure will be low so a pump is needed whereas in the roof, gravity helps somewhat.
Btw this setup is seen in East Malaysia but quite likely in big landed houses. In Sabah, esp the outskirts, they have it due to inconsistent water supply but instead of treated water supply, they use it to store rain water and their tanks are likely not metal but FRP or UV treated HDPE. Not that they dont have potable water tanks, they do but they also supplement.
If assuming this is landed terrace, due to space constraints, you want to site it such that the slab don't rest on the existing sewerage path below ground to prevent it from damaging them as well as unblocked access for future modification when renovating. Hence, the drawback is loss is real estate at the back esp in a small terrace or linked home and the risk of theft against the water pump. All this assuming that there's a model with a small enough diameter that dont take up much footprint.
As for the cover, usually they have cover but as stated as your requirement it suggests that the back of your place seems open like a communal ground rather than fenced up backyard? Best to ask the hardware store guys if there are models that have tamper securable covers ie it can take a padlock etc. Custom made FRP tanks can specify but those ready made stainless steel ones you have to find out.
Normally, what others usually do is to get a bigger tangki and site it on the roof and alter the incoming supply not to enter into the house but outside into the roof to the tanks and trace the path in reverse to kitchen and laundy or not at all. The latter usually because the bigger tangki now supply the whole house even the kitchen and laundry. The piping in the kitchen need to alter so that it's disconnected from the disused pipe from the front. The pump in the roof then serves the whole house. Again, roof must be able to support the load so easiest way is to add on and enlarge the existing one within the limits supportable.
