Plumber leak

[zaffy]

A few months ago, I hired a plumber. The part he replaced is leaking. I contacted him.
His reply was, "I no longer work for myself, your best bet is to call *********.
I can only presume the company that he suggested is the company that he now works for.
I messaged him back, "The leak is from the blending valve that you fitted when you were an independent plumber so just needs a slight adjustment from yourself."
I have had no response.
So what next?
Thanks.

Although legally he may be responsible for faulty work done when he was a Sole Trader if the cost of getting it fixed by someone else is small I would be inclined to get someone else to fix it. Do you want him messing around with your plumbing when he doesn't want to do it and might have left the plumbing business altogether?

In any case he might not be liable for the leak from the blending valve. Depends on why it is leaking and any guarantees or warranties he gave you.

Pallasathena, thank you. The leak looks like it is coming from the joins, and not the blending valve itself. Surely it is courtesy to pop round and tighten the joins.
But if the leak is coming from the blending valve then hiring a plumber to fit a new one will be in the region of £300.
This blending valve will still be under warranty because the work was carried out just a couple of months ago but I have no receipt from where the plumber bought it. Surely it is the responsibility of the plumber to remove it and return it to the shop or manufacturer and refit a new one.
The plumber's message recommended I contact a certain plumbing company I believe this is the company he now works for. So it would be ironic and expensive if I hire the company that the plumber is now working for and he turns up to repair / replace his own work and I get invoiced for yet another £300.

I used another company to repair the leak at the cost of £144. When the original plumber fitted the new part it had a missing washer. So simple, but so expensive for me.
