Plumbing - 3 port valve replacement quote

Hello,

The plumber refitted a new boiler for me (and did a nice tidy job) but since the install the heating and hot water have been coming on at the same time. This has been an issue historically with our system but hadn't been doing this for several month prior to the install.

Anyway, the same plumber has quoted £360 (inc VAT) for the replacement of a 3 port valve to sort the issue. I assume this includes draining down the system, the fitting of the valve, and the cost of the valve itself. He also mentioned chemicals. Is this the price you would expect for a replacement such as this?

Many thanks,

Alex

    Valve about £60-70 (to him)
    few quid for the chemicals
    allow half day
    remove 20% VAT

    Reasonable cost

    Have a look on youtube.

    The valve consists of 2 parts the valve bit and the little electric switching box that sits on top.

    If its the box that has gone (the vids online) are pretty good at helping you identify the issue then its worth trying it yourself.

    If its not the box but the valve then you can get someone in to do it if you are uncomfortable with the idea.

    Would also be wondering to myself why he didn't do this at the same time the boiler was changed as the system would have been off, drained, and it would have taken very little time to do a direct like for like replacement at that time.

    You mention this is a historic issue, did you mention it to him?

    Did he then suggest a new boiler as a result?

    Was the old boiler really in need of replacing or was it the 3 way valve that needed doing instead?

    Price is on high side in my view. Google the line below and watch the video... Worked for me a couple of times.

    A lot depends on how accessible the valve is. Some are easy to reach but if its hidden behind a boiler, in a small cupboard on the floor in the dark.........
