debris in hw/cw system

There won't be that much of it since there are normally no more than half a dozen holes.

On the HW side, any that has left the tank will almost certainly be in the bottom of the HW cylinder. It is inert and unlikely to go anywhere so I wouldn't bother about it.

I would just make a mental note that that plumber is a bit careless.

What holes are these?

OK cheers - any advice that means I don't have to do anything sounds good ;-)

Quite an elusive chap. Never answers his phone anyway so would be hard to use him again. Guess that shows how much work there is for plumbers. I'm a complete plumbing noob but he seemed to make a nice job of it otherwise.

The ones in the tank where the connectors to take the pipes are fitted. Normally a hole saw is used to cut a hole and then the fitting is inserted and held in place with a washer, possibly sealant and a nut.

There will be a minimum of three - for the ball valve, the overflow and the take off for the HW cylinder.

There may be additional ones for a vent for air and another to take the vent from the HW cylinder. Possibly there would be a second take off for cold for a shower.....

Ah see what you mean - I was thinking about the HW tank.

Thanks for the help.

If you ever have problems with the valve not sealing in the pipe feeding cold water to the HW tank, then you know what the reason might be. I once had a larger 'foreign body' (actually a young, very dead bat) fail to pass through that valve and block my HW supply (I had to drain the CW header tank and dismantle the blocked valve to clear it) I hope this information is never needed!

Don't think we get many bats here, but I live in hope. How would I know that was happening? I have 2 feeds from the loft tank, both have taps on as they leave the tank, one is the CW feed and the other is to HW system.

If the water runs slower, something's blocked. If it's the hot then the feed to the HW tank is blocked and if it's the cold then the CW feed is blocked.
