Prv combined condensate pump

[cdodds2004]

Fitting a boiler soon with a very awkward prv run.

Have seen a few into condense pumps.

Can any recommended a pump suitable as the ones I have seen
Are into normal pumps and I suspect they are not up to spec for
potential prv discharge? It's becoming quite common practice around
my way on boilers fitted under grants

Thanks

The prv pumps are different and come normally with a braided discharge hose plus more expensive.

It all seems a bit what if what if these days as there are a few manu's combining their prv's and condensates (Veissman and alpha intec2) and the prv connection to the condensate pipe is a bit plastic hose no different to any other bit plastic hose.

On the outlet of a standard condensate pump the hose is just a clear plastic hose as it's just pumping away condensate at say 50 degree.
On the outlet of a prv condensate pump the hose is thicker and braided as its pumping away condensate and or prv water at possibly 90 degree.

Here is a picture if the prv set up on an intec2 Lee. Made from standard clear plastic hose stuff.

very good pump used them about 5 times now no problem just wiring in the safety switch like normal

I know what you mean tamz
that product would be tested for its use and deemed suitable by the boiler manufacturer.
Same goes for the condensate pumps
One is suitable for just condensate the other is suitable for prv discharge and condensate.
If you use a standard condensate pump and hose that it is supplied with it then discharge the PRV in to it then it's wrong as it's not suitable.
If it was there would not be a market for see picture.

At three times the cost of a standard pump.
It looks like it has been tested and passed to accept 100 degrees the cheaper ones are only 50 degrees depending on make it does vary.

doesnt matter least your breaking the norm and know where to look and not fitting stnd cond pumps like others ive seen

 

[tamz]

I've seen them Lee but never had to use one.

Personally i would use a boiler that allows remote prvs eg vaillant or a combined prv condensate like the above. Saves a lot of faffing (i got that word off Croppie lol) around

If you use a boiler with a combined condensate and PRV and run the combined condensate and PRV in to a pump you have to use the correct pump you are still running the PRV in to a pump that may not be suitable for PRV (I assume you know this and this is a wind up)

 

[tamz]

I know it and if it came to it i'd ring the manu and follow their instructions as it is down to them.

It's still a PRV coming out the boiler which has to be terminated adequately there is one way if using a pump choose the correct one for the job.or a bucket [emoji16][emoji16]

 

[tamz]

Afaik a bucket is acceptable lol. The whole problem is there is very little regulation as to what is acceptable or not as a boiler prv is different to an unvented tprv so most of the guidance has to come from manu's.
Believe it or not in the 80's when sealed systems 1st started to become popular dropping it to the floor was an acceptable termination to BG even on an upstairs boiler. That is a fact cos i subbed to them at the time.

 

[leethegasman]

There's a pump on the market for a TPRV as well but that's a different subject.
I think your missing the point the fact is that some condensate pumps are not suitable to terminate PRV in to that's a fact.
Also terminating PRV direct to outside is going off track A bit the whole point of using a pump is because we can not terminate
Direct to outside.

I was on about dropping it to the floor inside

A fella I know who only fits glowworm had this issue once and ran prv into a f&e sized tank on floor of airing cupboard via a tundish. He checked it out with LBC and they were fine with it

The reason for using a pump is because there is no way that the water can run safely using good old gravity.
I don't understand how terminating a PRV in to a fe tank is going to solve the problem ? As once the fe tank is full it has to be discharged to a safe place and if good old gravity is not going to do it we need to use a pump that is up to the job.

Theory is I believe that if the boiler discharges properly it is never going to discharge more than the capacity of the tank. I do agree with your sentiment though if there is a continual unnoticed drip and the owner keeps topping up
