Some drain repipe valves do not take washers and therefore you cannot repair them. If you have a washerless shut-off valve that leaks it will need to be replaced. You will need: a propane torch, solder, flux, sandcloth, a wire fitting brush, a small section of copper pipe (most likely 3/4" I.D.), a slip coupling (again probably 3/4") and a shut-off valve. I would highly recommend installing a ball valve with a drain on it as opposed to a washer style valve. If you purchase a decent quality ball valve it will last a very long time.
A good company offers guarantees on their labor and the parts they use. Reliable plumbing companies guarantee their work Trustworthy plumber with written warranties and contractual agreements. If you pay for service and it fails, you will not have to pay for the same service again if the work is guaranteed.
Preventative care is what is needed here such as using commercial products for unclogging a drain and wrapping your pipes and having them insulated. You may also want to invest in drain covers for your drains to catch hair and grease before it becomes a problem that warrants the call to your Local plumber. If you have pipes outdoors that have hoses, before fall sets in, disconnect these hoses and bring them indoors. This is just some of the preventative maintenance that can be used.
Toilet problems: Plumbing works have to be done carefully in the toilets. Issues like clogged toilet, noisy toilet or running toilet arise when the plumbing works are not done properly or if here is any issue in the connections. When wastes get built up in the pipes, it becomes clogged and leads to lots of problems. You need to check if the pipes get cleaned automatically. When the toilet's fill valve is not fit properly nor has some issues, you need to replace it immediately to prevent any noise that comes on every flush. Also, when water keeps flowing, too much water gets wasted and in this case, you need to contact a professional plumber to solve these problems.
When you are ready to commission the work, ask for the quote in writing and ensure the final bill is broken down. That way, there will be no room for inconsistencies between the two figures.
