Sometimes the best solution to a toilet problem is to replace an old model with a newer one, which is one of the most popular Toilet Services that professional plumbers provide. Older toilets, especially those produced before 1994, use far more water per flush than new models, making new ones less costly to use. Not only are the latest models more efficient, but they are also more comfortable, with a roomy elongated seat. If an old toilet is rusty, cracked, wobbly, or needing frequent repairs, it is probably time to invest in a new one.
