Disappointing hot water flow from new tap

[Surefire]

Hi Chaps

Just replaced the old mixer tap in the kitchen sink with a shiny new one and am quite disappointed with the flow from the hot water. It takes an age to fill the sink. I noticed that the feed pipes to the new tap had a slightly smaller internal diameter to the old ones. I was thinking of drilling it out a couple of mm, as it is the hot water side and not subject to too much pressure would this be ok? or are there any other ways to increase the water flow (apart from raising the header tank to the same altitude as the himalayas!)

Thanks

You and a million other people who've bought the wrong taps.

It's usually the internal tap waterways that are the prime bottleneck, so there's pretty much nothing you can drill out that would improve the flow.

or are there any other ways to increase the water flow (apart from raising the header tank to the same altitude as the himalayas!)

1. Different taps.
2. Ensure that all other pipework is as free flowing as possible.
3. Add a pump.

Ok thanks for that Softus. Guess I'm gonna have to live with it.

We had same problem in our old house after having bathroom refitted.

We sold the house...

(Sorry, I know this isn't particularly helpful but shows that even with installations by "allegedly" professional people you can still end up with a poor result).
