question:
That would be alot of work, only replace what you need to. Unless it is your sewer line then i would replace it all to the main. I agree with answer # 1. IN ADDITION: Back in the day, cast iron joints were sealed together with hot lead. Depending on the position of the cast iron pipe and the size of it. Either one can cut the cast iron piping and clamp PVC to it or you can melt the old lead out of the cast iron joints and place PVC piping inside and then recork (reseal) it with prattley putty to prevent it from leaking. the flow of water: slow drainage is often the first indication of a problem, and homeowners may find themselves calling the plumber every six months to clear out the pipe. The average lifespan of cast iron drain/sewer pipe is 50 to 65 years. It is easily recognized by the thickened female "hub" at each pipe segment connection. Rust eventually eats through cast iron, primarily from the inside out, as shown in the photo below. Because corrosion is accelerated by moisture, pipe with light effluent flow and installed in a dry environment can survive 20 to 30 years longer. So keep cast iron piping or cast it out? Older cast iron waste pipes should be judged on a case-by-case basis. First hire an experienced home inspector to collect information about the drain waste system's performance. Ask your home inspector to do a visual inspection of the pipes if possible. If your inspector is any Trenchless Pipe Lining LLC matches that warranty with a 50-year labor warranty since the liner has turned into rock inside the pipe and cannot move, shrink, or be displaced in any way. Interestingly, the hardened pipe liner actually DOES flex a little which allows it to accommodate ground settlement without cracking, unlike clay or cast iron sewer pipes. Re: Cast Iron Drain Pipe - Life Expectancy. I simply put cast-iron and galvanized piping will rust from the inside to the outside and eventually will need updating. If mineral deposits are noted as reported as a leak. Also be aware I have found vent pipes totally rusted out behind the wall. A good quality cast iron pipe, installed under ideal conditions, has a life expectancy of 75 100 years, and possibly even more. Cast iron does rust but when it does the rust actually forms a barrier layer over the remainder of the pipe which helps protect it from further rusting. Since most cast iron pipes were thick walled to begin with even with some rusting inside they can handle the lower pressures of waste water disposal quite well and last a long time. Cast iron also provides many other benefits in home waste systems that still makes it a good choice for homes. For all of its good points cast iron does have some problems related to it. One of the problems had to do with the varying quality of the pipe that was manufactured in earlier years. Standards for cast iron pipe have been around since the 1800's but like anything else they are voluntary standards. Cast Iron and galvanized drain pipe may appear to be in fairly good condition from the outside. When I had some cast iron drain pipe replaced, we found sever... Cast Iron and galvanized drain pipe may appear to be in fairly good condition from the outside. When I had some cast iron drain pipe replaced, we found several potential problems that would have surfaced in the near future. The estimated life expectancy for cast iron drain pipe is 60 years. I couldn't find any good estimates for the life span of galvanized pipe, however, my 2 inch pipe from the kitchen drain was almost rusted closed. What kind of paint for a cast iron drain pipe? If you want to prime it first, latex is fine or oil base by itself. You can probably get by with latex directly on the pipe, but there may be oils or dirt on it that will blee d through. Query: how long does cast iron drain pipe last
answer:
The average lifespan of cast iron drain pipe is 50 to 65 years.

question:
According to the USDA: Storage Conditions: Lettuce should be quickly cooled and maintained as close to 0 C (32 F) as possible with 98 to 100% RH. Head types are better adapted to prolong storage than are the other types, but none keep longer than 4 weeks, and about half that time at 5 C (41 F). Squeeze the air out and close the bag. 5. The lettuce can now be stored in the fridge & should stay fresh at least a couple of weeks. You can take out what you need whenever you want to make a salad or sandwich & then just reseal the bag.

I separate the leaves and let them sit in a sinkful of cool water for 5 minutes or so. Then I rinse them well and drain well.

For iceberg lettuce I ususally try to wash it at least a couple of hours before I use it by removing the core and letting cool water run into the head. Let it drain for a few minutes, then wrap it in paper towels and put in a plastic bag, then into the fridge to crisp for a couple of hours. It gets really nice and crispy.

Category Entertainment Washing lettuce may win as my most hated kitchen task. But if I wash the lettuce right when I get home (I use a spinner, but you can also just spread it out on the counter), place it in one layer on a kitchen towel, and then roll it up into a kitchen towel-lettuce spiral (see above), each leaf stays unimaginably crisp and fresh in the vegetable drawer for up to a week. Put your lettuce into a nice big bowl, and drape a paper towel or two over the top so moisture doesn't settle on the leaves while your salad sits in the fridge. Cover the whole thing with a really tight seal of plastic wrap, and store. A little salt and pepper or seasoning can punch up the flavoras long as you add it before serving! Usually sellers hold the lettuce at room temperature during the hours of sale (to show to buyers) and place them in the refrigerator in the night. But attention. The supermarkets assemble the heads under plastic films (as said), which retain moisture, and daily keep them anyway in departments fresh.

When a warm air mass meets a cold air mass, they don't mix as they have different densities (a bit like oil and water). Instead, the warm less dense air is pushed up over the cold dense air creating the 'front'. Convective rain, or showery precipitation, occurs from convective clouds (e.g., cumulonimbus or cumulus congestus). It falls as showers with rapidly changing intensity. Convective precipitation falls over a certain area for a relatively short time, as convective clouds have limited horizontal extent. Describe how does precipitation occur and what determines the type of precipitation that falls to Earth? Precipitation occurs due to the immense collection of water vapor in the form of clouds. When the water vapor in these clouds gets too heavy, it falls. Rainfall intensity is classified according to the rate of precipitation: 1 Light rain when the precipitation rate is < 2.5 mm (0.098 in) per hour. 2 Moderate rain when the precipitation rate is between 2.5 mm (0.098 in) - 7.6 mm (0.30 in) or 10 mm (0.39 in) per hour. Rain & Floods How does rain form? Water droplets form from warm air. As the warm air rises in the sky it cools. Water vapor (invisible water in the air) always exists in our air. Warm air holds quite a bit of water. For example, in the summer it is usually very humid. When enough of these droplets collect together, we see them as clouds. Most of the condensed water in clouds does not fall as precipitation because their fall speed is not large enough to overcome updrafts which support the clouds. For precipitation to happen, first tiny water droplets must condense on even tinier dust, salt, or smoke particles, which act as a nucleus. Precipitation - Measurement. 1 The standard way of measuring rainfall or snowfall is the standard rain gauge, which can be found in 100 mm (4 in) plastic and 200 mm (8 in) metal varieties. [74] 2 Other types of gauges include the popular wedge gauge (the cheapest rain gauge and most fragile), the tipping bucket rain gauge, and the weighing rain gauge. Query: how does precipitation occurs
answer:
Precipitation occurs when cloud droplets combine and grow large enough to fall to the earth the rate of evaporation as a drop falls to the earth also can affect its size.
