Leaking toilets: has your water bill suddenly increased? The most common cause that we see is a leaky toilet. Leaks can happen at the float and overflow, or the flapper.

Trap seal primer: a trap primer (or trap seal primer) is a plumbing device or valve that adds water to traps. Sometimes they can stick in the open position.
