I have a conditioned crawl space which is only 6 yrs. Plastic foam pipe wrap is obtainable in a variety of lengths and dimensions to fit different sizes and it is easily cut with scissors to obtain the desired lengths. When the shower was turned off, the humidity started to drop at ceiling height quite quickly - but only to about 85%. You need to look for the 'get out' clause in all of their contracts. The paper has gone mouldy - the glue has rotted, and the whole thing is horrible. A recent survey provided a fantastic example. This operates for an hour or two a day, and draws warm, dry air from the house into the cellar, and pushes cold, damp air out from the vent fan to the outside. For pipes that bend, or have elbow shapes, wedged notches can be cut out to allow the insulation to curve with the pipe. Please help me. From your description, I see several problems that could be causing excess moisture in the crawl space under your house: I put some plastic on the dirt crawl space in 2008 after purchasing my newly build house. As such, the only way that water can condense on your ductwork is if one of two conditions exists: First, if you don’t have adequate insulation on your ductwork, and second, if there is excessive moisture in the air. If your heating/cooling … Hi, I really appreciate you guys first of all!
SciFi novel about a vault on the Ocean floor.
We know that the air can only hold a limited amount of water, and that when it reaches this limit it has 100% humidity.

Can I prevent my tub faucet from leaking by diverting the water to the shower, and shutting off the shower head? Save my name, email, and website in this browser for the next time I comment. If you've found this site useful, please share it with your friends!
Or use a slotted pipe w/ a drywell at the end and spread it out more Nate R, Sep 13, 2008 #6. droemer New Member.
Air conditioner drain lines are made from PVC (white plastic). Thank you.
Older homes may have pipes situated near electrical systems, breaker panels, or electrical junction boxes and pipe sweating near these fixtures is hazardous. Sometimes, the art of writing lies in thrift. Any clues what this would be called? Can bacteria be killed by purely physical trauma? Look up the directors and sources of finance. This reading is nearly always false. It is the heating/cooling system condensation drain line. Ian Rock has written another of his great books. There trunk line and the branches are all insulated as well as the walls and there is a vapor barrier on the ground which is covered with gravel dust under the vapor barrier. I have seen furnaces in garages that drain into a planter as described and there is no issues, it depends on where your unit is, where the condensate lines go, if its in the attic you have primary and secondary drains. So don't think it only happens on surfaces - if your walls are cold, it happens INSIDE the wall, dwhich is the real cause of the symptoms called 'rising damp'. We like absolute - it is measured in grams per cubic meter. If you're in the market for a new AC or furnace, make sure that you get a fair price! This is because metal is very good at transferring heat and also why it is a horrible insulator.
Condensation in old houses causes the phenomenon most commonly called 'Rising Damp'. Your 'damp' is easily diagnosed, and it won't be rising.
If you see water leaking from a pipe outside your house, the first thing to do is identify where the pipe is and what material it’s made from. The solution is to remove the render and let the walls dry out. Try our online calculator; click the tab on the top of this page for more information. Marco plumbing is pleased to offer a 10% Seniors and Military Family Discount. I live in LA and my 60 yr old wood floors are now buckling. Why Is My Air Conditioner Freezing Up? So far my searches only turn up hoses for interior use. Just like when you have too little insulation, if you have an excessive amount of humidity near your ductwork, either in your attic or crawlspaces, then you increase the likelihood of condensation forming. The example in the image below if from the EPA in their guide for moisture control around the foundation. He's worked all over the world on old buildings, and has a strong background in geochemistry. It is dripping because there is more condensation. Think about it, if you touch the metal side of a frying pan on the stove, you get burned right?
4. In another survey, the client was using gas fires to heat the place.
A great book, with lots of practical information you need if you have an old home. Firstly: Condensation does not just occur on wall surfaces. The next step is to ensure that you add a vapor barrier to your ductwork. @hadfield_jean @MartinSLewis Pretty normal numbers. Not all the guide will be useful and its not exactly your situation, but you can check it out here. If you follow all these rules, your house will be a lot drier, and condensation won’t be a problem. Pipe condensation occurs when airborne moisture comes into contact with a cool surface, such as a cold water pipe. This lot has again trapped water which has managed to get out at the skirting level where the plaster stops, and destroy the skirting boards - very nearly creating enough moisture to start dry-rot. The location of the pipes that are sweating may necessitate professional remediation. Size-wise this pipe or PVC fitting (a 90°angle called an elbow) is about as thick around as the circle created when you put your index finger and thumb together (3/4”).
My thoughts was to turn my ac to a higher reading, close my vents, seal the walls down to the vapor barrier on the ground and add a dehumidifier and monitor humidity from there. A representative from NextGen Air (BBB A+ rated) will be calling you shortly to confirm your appointment.
However, you only need to inspect and flush your condensate line before the cooling season. Put a drainbox under the line and extend a hose from the drainbox away from the home.
IMPORTANT: If the AC drain line up high near the attic is leaking water, call your local AC company for service immediately.
Do you have any other suggestions why after 60 years the floors are buckling? Don’t like it, vote t… https://t.co/ePZrz7v517, Just about everything associated with trustmark is a fraud.
In this case, there will be no secondary drain pipe up high. It will consist of covering every area of your ductwork with at least one layer of wrap. If the water is not running away from your foundation and sitting stagnant against the it, I would drain the water. He complained there were damp patches all over the house, and mould growing on clothes and belongings in cupboards. I think the amount dripping is actually more like 5 gallons a day (another wild guess, but it is actually a thin little stream rather than a drip). Your specialist will The water lands maybe two inches from the exterior wall.
At All Systems Mechanical air conditioning and heating, we believe that the experience our clients have is every bit as important as the products they receive. Many people don’t even know the air handler is part of the air conditioning “system” and think the unit in their attic is just the furnace or heating system. At my dad's suggestion, I just added flexible pipes to divert the water from our gutters away from the house.
It is leaking water, this is good because the pipe is clear. Call today for more information.
The atmospheric temperature at which the air is saturated with water is called the dew point. We NEED to be aware of this, and make sure that the house can breathe and ventilate. Some are caused by penetrating damp - simple things like high ground levels or leaky gutters and downpipes. I have insulation between the floor joists with plastic stapled underneath.
Can I wrap that with some type of insulation-tape? A lot of the difference though, is geographic location of the home, and whether the ground around the drain slopes away from the house or is flat. The disturbing fact is that it took over 4 hours for the humidity in the room to drop below 70% - in other words, with average house temperatures there would have been condensation forming for 4 hours or more. Note that your survey does not just include damp and condensation problems - we check the entire fabric of the house for any other problems - structural, timber, plumbing, roof and so on - in other words, a full health-check on the entire house.
By submitting this form, you consent to receive a call, email, or text from a Um - what the hell are you paying for a homebuyer survey for, if the idiot of a surveyor can't even diagnose the real reasons for timber and damp problems - he has to recommend a chemical salesman who has NO interest in solving your problems, and a HUGE interest in making money. The amount of water you see will depend on the humidity level in the house. Pipe condensation occurs when airborne moisture comes into contact with a cool surface, such as a cold water pipe. If you come home to find a small puddle of condensation near the drain pipe, that is normal and a common effect of an air conditioner working hard—particularly on extremely hot or humid days. Either way, removing humidity from the air in your attic might be the most cost-effective way to handle your problem. Condensation forms when warm, humid air comes into contact with a colder surface like your air conditioner’s ductwork.
Hi, Alan, Danny says, “I think your approach is a good one; it definitely is moisture related; the dehumidifier will solve that problem. What to do when your bank or building society tell you to get a PCA timber and damp report. If you are already familiar with what causes condensation, then skip to the next section. We tested the temperature and humidity of the walls. If the water which forms as condensation can evaporate - through lime plaster, or lime mortar or stone, it goes as soon as it forms - just evaporates away like rainwater on your paving stones dries when the rain stops. Besides the spiders, mud wasps and other creepy-crawly’s that like to hide and nest in these pipes there’s the “sludge”. Scary stuff, I know - but you need to know the facts!
