Hi

It was apparently working fine - then an overflow problem - now it doesn't
have sufficient siphonage to take away a piece of toilet tissue!

It's a close-coupled toilet (25+ years old) which originally had a problem
with its overflow. A friend of my mothers replaced the existing toilet
siphon with a push-button flapper toilet cistern valve, which incorporated
an internal overflow - solving the overflow issue. However, now it has a
poor/weak flush.

When the toilet is flushed, water seems to emanate normally around the bowl
rim, the bowl water level rises and then returns to its normal level but
with no particular siphon whoosh, which results in a simple test piece of
toilet tissue remaining in the bowl.

The only things which jumped out at me (I don't mean that literally) when I
looked in the tank was that the water level was lower than the waterline
mark on the inside of the tank (approx half the depth), and the bottom
entry inlet valve looked quite short.

I have tried holding the float down to allow the tank water level to raise
to the waterline mark (which takes the water level over the top of the inlet
valve) - this produced a more significant flush which took away the toilet
tissue, but I doubt that it would have taken away much else.

I have checked the external drainage which appears free flowing - the only
other thing that crossed my mind was whether a plastic toilet bowl blocks
which should hang off the rim has fallen into the bowel and become trapped
in the bowl siphon. Although, Im leaning away from this as it would have
thought the issue would have been apparent prior to the flush mechanism
change.

I have also tried tipping a bucket of water into the bowl which seemed to
result in better bowl siphon.

I beginning to think that the problem is associated with the 'quantity and
speed' of the water entering the bowl and intend to nip to my mothers to
have a closer look at the rim holes to see if they are restricted in anyway
and also look to see if the flapper can be adjusted in anyway.

Does anyone have any other thoughts?

Thanks

At 25 years old it's almost certainly wasting water no matter how it
flushes.

Get a new system, designed for water saving and with a dual flush

I think the fact that you are using old and new 'technologies' is the issue.

I suggest that you raise the water level to where it should be and then
think about changing to a new WC and cistern.

If water is not leaving the bowl as fast as it is entering and the water
level simply rises and slowly subsides, this is likely to be a blockage.
I too have had similar syptoms when a bog cleaner thing got lodged in the
pan waste outlet.
Do you have more than one item discharging into the same drain as the WC?
If so check the rate of flow from other devices compared to the WC just to
get a "feel" for a good flow. Then flush the toilet.
If it's leaving the bowl slowly then you should notice the difference.
I would try one of the spiral wire drain cleaner thingies down the bowl as a
starting point.
IMHO changing the cistern and bowl is most probably not necessary.
I deliberately reconditioned and kept my old cistern, boxed it in and fitted
a new bowl as I didn't want to end up with a pathetic 3/6l flush (I already
have this in another toilet and find it hopelessly inadequate

Ours is excellent!
