Intergas Rapid 32... THUD! Noise when hot water is running

[joec_85]

We had our heating system replaced in March with a combi boiler system. It's all been working fine. About 9 weeks ago, I replaced a faulty kitchen tap with a mixer. Again, it's all been working fine until now.

This morning, when running the hot water past a certain strength, there is now a THUD noise followed by a drop in pressure. Turning the tap off and on again tends to reset the pressure until it gets to a similar strength and then THUD it drops again.

The other taps in the house seem to be working fine.

Does anyone have any ideas? Air lock? Faulty tap?

Thanks

It’s an Intergas Rapid 32

doubt that it is a boiler problem , think it is a tap problem, but some Intergas experts on here, change your post title and add Intergas to it and you will get theire attention
