Welcome to Hometalk.
Water pipes can be run through the ceiling and I don't think it's all that unusual, but you have to be especially careful to avoid freezing because it can obviously cause more damage and more expensive damage than frozen water pipes in a crawlspace.
I think they were run thru the ceiling to keep them from freezing. I bought an old house (fixxer upper) and it has a very small to non-existent crawl space. The kitchen & back bedroom have drop ceilings and I am in the process of removing them and putting in a sheetrock/drywall ceiling. My neighboir is a contractor and he mentioned that I should re-pipe the pipes ( they are small) to under the house. Our county code does not say this is mandatory so I am worried about borrowing more trouble if I do move tjhme.
i'm the owner of condo built in 1972. The old water line pipes had have been installed under the slab which now started a leakage which is hard to determine at what point it leaks. As of today our HOA decided to repipe in the 2- story buildings where units stack on each other. The units downstairs get affected by the repiping project more than units above. HOA have started fixing a leakage from the building next to mine. Hired contractors have started drilling the slab and digging the ground to remove old pipes out and replace them with the new ones, it was UGLY mess of concrete and soil,inside of the units, and it did COST a lot of money to HOA!!! HOA decided not to afford have it done so costly for each of downstairs units. Now it's my unit turn. Contractors/HOA decided to route new water lines thru the ceiling instead of old way: firstly, to save money, and secondly, the water leakage can be seen faster, if any. Today March 3, 2019, contractors started repiping my unit, and did cut my walls and ceiling in many places (BIG HUGE mess, hard to stay home because all belongings stacked in corners). They planned to finish project in two weeks, and we have to live in such inconvenience!
My big concern of the decision HOA made of routing water line pipes through my ceiling is if it could affect my condo price?
Pipes are typically more likely, not less likely, to freeze in an attic, so that shouldn't be a concern for you. I think if the pipes are insulated, they should be OK up there. Moving them won't be cheap, but it could avoid some costly repairs later if they do freeze.
Steve, Sorry but that blanket statement is not always true, esp given the small amount of information given here.Climate, Crawlspace conditions, whether the pipes are above or below the insulation and how the attic is vented are variables that effect this. Some attics are conditioned space as well, so pipes can be far less likely to freeze there
Jeanne, Since your neighbor is a contractor and has seen this, it is likely that he is right, but is he at arms length or is he trying to sell you a job?
If these have been there for a few heating seasons, they are time tested and OK - probably
If you are gutting and redoing everything anyways, now is a good time to make the decision tho.
If you re-run the supply lines, consider PEX which is flexible and easier to run, and is more freeze resistant
if you smart, you could understand that PEX for hot water is not a good decision. You should know about the "plastic pipes"-polyethylene has ability to taper and expand back and force as hot water run on and off, and such condition more likely creates a leakage in between joints and pipes! And not only this, the screw tracks of flexible PEX pipes and joints are so soft that may get easily smashed during screwing them in that also could cause a damage to screw tracks smoothness and more likely could create a leak soon. I live in CA, and our HOA now runs re-piping project with copper pipes that they decided to install through the ceiling of frist floor units because the old way through the slab is very costly!
What kind of pipes and how old are they? If they are galvanized, get rid of them now. In your part of the country, pipes can free in the crawlspace but if you insulate them well and remember to let the faucets drip slightly on those super cold night...you'll never have a problem.
We try to advise clients against installing drywall ceilings here in GA because eventually...EVERYTHING leaks. They make some awesome tiled ceilings now that are perfect for basements. Here, you are updating the kitchen and bedroom ceilings so may as well rework the pipes while you are at it!
basement is OK, but if condo built in 1972 without foundation, which means no crawl space, but water lines were hidden under slub of the first floor units, then repiping through the ceiling is less expensive at least.
Good points, Nichter. Thanks for the clarification. I wasn't really thinking about all that.
Thanks to every one for responding. The pipes are water line pvc and they are routed thru the walls and ceilings in several rooms. this was a foreclosed home and according to my neighbors there had been several families living in the house. So I am guessing that is why the pipes were routed the way they were.
I am going to have the pipes re worked to go under the house(if possible) I have a few more big projects with my home and I am trying to do it correctly as I go.
if you have crawl space, of course, under the house is the best solution, but if no such space, then route the pipes via the ceiling is less expensive than route them through the slab.
