The next in the list of the types of sailing ships is the bulk carriers. They carry bulk cargo items. Coal, cement, grain, etc is carried in these ships. They are generally very huge in size. They are designed so that they can load cargo in bulk and also unload the cargo easily.
Typical costs: 1  Do-it-yourself replacement of a leaking toilet shutoff valve typically costs $10-$25 for new parts; requires no special tools or skills; and usually takes 1-2 hours. Broken or failing parts inside the tank (like a fill valve, flapper, ball cock or tank lever) may cause a toilet to run continuously. DIY replacement parts for this problem typically cost $5-$50 depending on the brand of toilet, with an average cost of less than $25. This project might take 20-30 minutes or two hours.
If water from the tank seeps around the flapper and into the bowl, the flapper is probably shot. Test for a leaky flapper as shown in Photo 1. To replace the flapper, first shut off the water supply valve under the toilet (or the main supply if the valve leaks!).Flush the toilet to drain out most of the water, and unhook the old flapper. Buy a new flapper of the same type and install it according to the instructions on the package.hoto 2: Check the fill valve for a leak. Flush the toilet and look for a fill valve leak. Lift up on the float arm when the tank is filling to see if the water stops. Bend or adjust the float arm so the tank stops filling when the water level is 1/2- to 1-in.
