Suggestions on Pump to Filter Connection

I just don't like the hose connection from the pump to the filter. The hose has no give to it and it's a little too big for the connection, yet I have the size down and it's a little too small for the connection. The hose is strained where the ends are glued on and it ends up leaking. I applied some silicone and it solved the problem. I would just like to replace that hose all together with something more reliable.

Problem is that with my pump the union nut that I need is next to impossihble to find. I could take the hose I have now and cut off the union nut that I need.

Wondering what suggestions/options are there for replacing this hose. I live in Mass and this is disconnected every season to take the pump indoors so I want something that can come apart fairly easily.

Here's a picture. Oh and my pump doesn't have internal threads that's why I need that so hard to find union nut. Brought it to a pool store and every nut they have it either too big or too small. I was able to order a part that goes on the pump first that will give me a male end with threads to work with.

Are both of the ends the same thread? Can you turn the hose over and attach it the other way? The reason I ask this is because you could get two male adapters, one for the pump and one for the filter, and then get two female PVC adapters and put a pvc union vertically in the middle of the connection.
I have never seen the connector hose like yours, but I agree with you, I don't like it either. Funny what engineers will come up with, you have tried and true methods that have worked for decades, and all of a sudden they have to try some new way of doing things, and of course everyone who saw the design and plans had to have loved it. I love plumbing, always trying to reinvent the wheel.

No the side on the filter is the standard 1 1/2" and is threaded on the inside and the pump is some weird size a little bit less than 2" and threaded on the outside. I've seen pumps at the store that have the threads on both the inside and outside, mine doesn't.

Once I have the part in that I ordered and cutting the hose I currently have to get that union nut off I will have 1 1/2" male threads on both sides.

So with that idea would the whole connection be PVC or do I have hose too? I'm sorry for the ignorance I'm new to PVC. I did look up what a PVC union looks like, is that what would come apart at the end of the season?

Hi Nicole, your pump and filter appear to be an AstralPool blow-molded Millenium model with multiport valve on a monobloc (made in Spain), we have the same model series (our filter cannister is larger) and it seemed to me that most, if not all, of their piping is 1.5" although perhaps their threading is metric! Maybe someone has actually measured it or contacted AstralPool and asked them ( www.astralpool.com ) I've sent them a request since I'm also curious about our setup. If they respond, I'll post here.

Out of curiosity, is your pump like ours, the dual speed unit (SENA pump model SEN1815 with a "Vernis Motors" electric motor)?

My pump is the 1800 (Model 1815) Series Single Speed, 1.5hp with a Century Motor.

Nicole, cut the pipe 1 1/4" from the effluent union. Use a 1 1/2" coupling to connect the new pipe. If you are not happy with the existing plumbing, just replace it! If you need any help with how to do this, just ask :) -Waste

That is a quick and dirty way to fix it. I like it, you would need a barbed connector to splice the new hose to the old hose left at the pump, and a male adapter for the filter side, and then you could use a regular pump hose that is available almost anywhere. You could order the fitting and do it differently next year if you like also.

I already ordered the part online, hopefully the right one. Once that comes in I'll have 2 male ends.

So from what I'm reading I can buy 2 female adapters ( 1 1/2") and some filter hose and make my own hose. Is it ok to use hose clamps on such a high pressure hose?

And if the part isn't the right one, I'll cut the old hose near the pump and put a male connector into that end. With the barbed connector you still need a hose clamp correct?

Interesting that I was at the local pool store and he couldn't come up with one single idea for me to make a new hose. At first he sold me a male connector and said ALL pumps have internal threads. I told him I was 75% sure it didn't and I get home and of course didn't have the interal threads. Drove the 1/2 hour back to the pool store and that's when he was at a loss.

He did have one idea and that was to cut out a big piece out of the hose to fit better and then to glue a PVC piece into the middle to connect them. From what I'm hearing I could cut the piece and use a barbed connector and then I wouldn't have to worry about using glue. Can I find these connectors at Home Depot or do I have to go back to that pool store?

You should be able to find the connectors at home depot, but they are funny with some things they carry. The pool store would probably have them, or else I have found Ace Hardware better sometimes for some of the odder fittings. I would think that a 45 degree or 22 degree bend up by the filter would make the transition a little better too.

Hi Nicole the connection on your pump looks like the one that came with our Proline Sand filter. The end going to the pump wouldn't fit on our Hayward motor so we went back to Namco and they used a clear plastic hose that my DH tightened with clamps. We used it this way without a problem for several years.:o
