There are other skills plumbers need aside from being able to work with water. One of the most common things that a emergency service on is fixing water lines.
Examine the washer and replace it with a new one. Also replace screws in water line repair case they are old and damaged too. The new ones you buy should be durable and of good quality.
After you have the stems out you should be able to find the washer on the "inside" end. If it is nicked, torn or brittle it is likely the cause of your drip. Even if it looks brand new, go ahead and replace it. You've already come this far. You can get replacement washers at almost any hardware store. Sometimes you may want to replace the whole stem, especially if the handle end is stripped out. It's best to just take the stem with you to the store and see if you can match it up. Most Do It Yourself stores have replacement stems for many popular brands. If your valve has a center diverter valve to switch the waterfrom the tub spout to the shower head the same process applies. Many times it is easier to replace the diverter stem than to repair it. This really depends on the design of the stem.
Service magic only let's licensed and insured tradesmen advertise on the site so that would be a great place to start. I would recommend getting at least three different quotes from different companies. This way you have an exact price of how much your works are going to cost and you will know exactly what you are getting for your money. You will also get the very best price for that work. Most plumbers will often try and sell you work that maybe you don't need as they are trying to make a living.
Plumbers, like all other companies, are required to be on time and act professional. If they have called before hand to notify you then, this can be overlooked. However, if they turn up without apologising for being late, then they may not be the right plumber for you. Remember first water line repair impressions are everything. If they lack a good first impression then this may indicate that it is going to have an impression on their work. In most cases, you would have taken the time off work for the plumber, and what can be worse than waiting all day waiting for them to arrive?
If you do in fact choose to replace it, there is a good chance that you have an Aqua Magic IV which is no longer produced and has been replaced with the new Aqua Magic V. If you are replacing your toilet and have the Thetford Aqua Magic IV, there are other options such as the Thetford Aqua Magic Style Plus or Thetford Bravura Toilet as well as choices from the Sealand line of toilets. You will have to choose whether you want a hand or foot flush, and whether you want to stay with plastic or upgrade to china. You will also have the choice of adding a water saver. Regardless of which choice you make you will most likely be happy with the quality and dependability of any product available.
The next huge thing is to prevent and kill mold that has already started growing. Mold is the most dangerous thing when an area floods. Mold can turn deadly within a extended period of time. Use mold killing agents like Killz and other products on the the market. Be extremely thorough with this process. If the water flooded above the dry wall line, you MUST remove the dry wall to make sure you can replace insulation and dry wall which mold naturally is attracted to. Painting a Killz primer on the concrete is a great idea before installing new carpet and drywall. This will ensure that you have prevented future mold growth and will also ensure the safety of your family.
