Actually, that's the right thing to do so that the substance you are titrating will all remain in the solution and not on the sides of the flask. But you should not use too much water because it will affect your result, water can dilute the solution so much, so instead of seeing the color change at the right amount of titrant, you would end up seeing it much later, when you have added more titrant.

Is it acid-base titration? if it is, then yes it affects your computation heavily.
If you add just a little water, that will change the sought equivalence point. Since water can act as a lewis acid or base in the reaction, it will lower your pH if you're equivalence point is greater than 7, vice-versa, thus changing the used mL of the titrant. Just think of water as a "contaminant", in acid-base titrations.
So whatever you do, do not rinse the sides of the conical flask with water.

on condition that you're titration for the volume of water or the water impacts the titration reaction. In both circumstances, the titration might want to br taking position in a solvent except water. if you're titrating in a water answer, including water gained't replace the effect. As a life like be counted, you want to apply water to rinse down the walls of the flask even as you're doing the titration with the intention to keep each and every thing interior the answer.

If you have place your titrand in the conical flask, it will not affect the reading from the burette because the number of moles of titrand is still the same. but if titrand is reactive toward water, it will be affected. If it's the normal acid base titration, it will not be affected.

no effect as the calculation involves moles of acid and alkali and distilled water has no effect

Yes, if the water is distilled, the results will be more accurate due to less impurities.
