I think something is wrong near the flapper. I can get DoItYourself info stale the web, but I want to know a moment ago how easy is it to do it myself. When should I phone the plumber? Is a plumber the one to call?
Answers:    The flapper stopcock controls the flushing, so if it is leaky, a new flapper (easy to replace if you obtain the right one for your brand of toilet) may fix it, or it may not - if the seat is eroded, a exotic flapper won't fix the leak - you will want to replace the entire seat, and that requires rather more skill because you'd need to disassemble that. You can recurrently run your finger around the seat (not the one you sit on, the one within the bottom of the tank below the flapper!) and feel for any spots that aren't smooth. If it's not a big dribble, I've been competent to use very fine sandpaper on the form to remove enough near material and smooth out the negated such that a new flexible flapper tap will seal in need leaking.

If the teem pressure is inadequate, that's a intact different part of the toilet. That could be something as simple as the shut-off spigot is nearly closed (some people do that to avoid getting scalded surrounded by the shower if someone flushes the toilet while they're in there), or if there's closely of grit and mineral deposits in your hose supply, it could be clogging the valve.
Not exactly sure what you denote by no pressure. Unless you have a reservoir with one of the pressurized bladders within it, there's no pressure other than that of the 1.6 gal. of dampen rushing into the bowl...
